work 80 hr/wk, need meal ideas

Make some sandwiches with plenty of (lean if calories are an issue) meat.

Boiled eggs if you can handle the fat calories.

I'll often take salads to work that take about 5 minutes to prepare. Could easily prepare several days worth at once - well, with what I eat, it'd typically be several portions for most people anyway :P...
Lettice, Tomato, chicken, ham, onion, sprinkling of cheese today and an egg. Lower calorie caeser dressing.
Meant to stick some apple in, but left them in the van and meant to stick some potatoes from yesterday in but forgot... and the calories were going up as it was.

Not sure what type of diet you follow, but I do know a lot of meal replacement shakes have a bunch of garbage ingredients. You could try making your own with egg white protein (whole egg protein is still way too expensive, IMO), cocoa (or cacao) powder, coconut oil (help keeps you full), milk of your choice - and boom protein shake.

Or, play around with it and add fruits and veggies (sans cocoa powder in this one lol).

Quick meals - do you have a day off, or a shift off? You could use that time to prep stuff, or if you can afford it - buy pre cooked meats and throw meat and veggies together in a skillet and experiment with different sauces. Throw a side of fruit on there as well.

Eggs, beef jerky, and pre cooked bacon are my staples for quick nutrition.

That sounds great! I think it'll be cheaper in the long run too, making it yourself instead of buying into those products. Way back in a previous life, I worked 16 hours days 5 days a week - I lived on coffee. It was brutal. I have higher standards now than I did when I was 18 (in terms of food), but I remember surviving on pre packaged meals, bologna sandwiches, and mountain dew. I hope you don't have to go that route! Prep as much as you can when you aren't at work (even if it's just an hour). Buy a cooler and keep it in your car or by your desk, that way you don't take up too much room.

If you're going for fullness - pack in the fat and protein, you'll stay full longer and have the energy to get through the day.

Perhaps not something you want discussed in this thread, but perhaps you may want to consider making a drastic life change? What sort of life is one where you spend 75% of your waking life working..?

if you add chia seeds and/or greek yogurt you can get full quick on shakes. I do the overnight oatmeal many times and that keeps me full until lunch.

1/4 c old fashioned oats
1/4 c greek yogurt (plain)
1/3 c milk
1 T chia seeds

that's your base... you can add fruits/nuts/jams as you wish to make your flavors. just make sure it gets at least 4 hours in the fridge

I have to agree, you seem to spend all your life working, eating & sleeping!

Maybe consider some canned / bagged foods. Something like cans of chicken, black beans, and a box of minute rice can be stored without refrigeration and made in a microwave on your work breaks. Those little pouches of flavored tuna. Frozen vegetables in the steamable bags. Potatoes can be stored without refrigeration and then microwaved when you need them.

Maybe some canned items combined with a few crock pot meals will give you enough variety.

do what i do:

step 1 : buy big *kitten* package of fresh chicken , boneless skinless. 5-6 lbs is perfect. you're also gonna need those plastic containers that are listed as freezer and microwave safe. they're like 3 or 4 bucks for 5.
step 2: take chicken out of package. if desired, trim fat. weigh out portions according to how much chicken you like. I started at 10oz, then 8oz, and now i use 6oz.
step 3: season and cook the chicken. store in the plastic containers. one serving per container. I don't use oils or butter or anything, just seasoning and throw them on the grill. easy.
step 4: put enough containers for the next 2 days in the refrigerator, the rest in the freezer.
step 5: bring enough containers plus enough bags of steamer veggies for your day. each meal is 1 container and 1 bag of veggie. here's a pic:

You can get these or their generic equivalent for around 1.00 - 1.50 each.

And that's it. high protein super low cal meals that are budget and time friendly. I eat this crap all the time, flip through my diary and you'll see it frequently 2 times a day. Add sauce to taste. Hot sauce or a1 works really well

Can you leave food at the fridge for multiple days? Or will someone toss or eat it? Is there a microwave?

How about a grain type salad? Bulger, barley, quiona? Add in substantial roasted vegetables (eggplant, onions peppers), lean proteins (roasted chicken, grilled tofu, or beans). Add in a nice vinaigrette I like lemon juice, dijon and olive oil, it gets better the longer it sits. It can be eaten cold or room temp.

Sandwiches are certainly easy, but the bread can eat up a lot of calories. Try substituting a large lettuce leaf or eat only half a sandwich at a time with something else.

Small containers containing small amount of raw, roasted nuts, cottage cheese, hummus, grape tomatoes and any other cut up vegetable like jicama, carrots, cucumber, celery, can be great snacks to supplement smaller meals. I assume you get some sort of break.

I have made an egg scramble or oatmeal in bulk and carried it to work for later.

I used to roast vegetables and sometimes a whole chicken for future meals and have them on hand to add to a salad, grain or sandwich.

I don't envy your schedule. But don't succumb to fast or take out food. It certainly takes some planning and a little prep time, but learn to cook once and use for multiple meals.

As others have said cook in bulk and put 2 servings in the freezer. And one day, when you haven't planned, you grab something from the freezer.

I've also taken a few hours cooking with a friend. We knock out 4 or 5 meals in a few hours. You've got someone to share a few meals with along with the work. Win/win!!
