No fridge, no microwave meals on the go...

Hmm I would say look into those ice packs for lunch kits.

Yes... I'll be going back to working 2 jobs so I pack all my meals on those days. I bought a large lunch bag, and several of the ice packs. I've had no problem with things getting too warm or going bad.

I'm a fan of those "Go Picnic" meals. They are shelf stable, no refrig needed, and between 300 and 400 calories. I have tried several, and I think they are all good. I pack them when I travel. I find them at Super Target in the aisle by the dry mac and cheese, for around $4. Add a piece of fresh fruit, like an apple or a banana, and I think they are a satisfying meal.

From another site...

Day 1 - I make a really good barley salad that is very healthy and can be as cheap or expensive as you want it to be. I don't really use a recipe, but basically you boil barley until it is tender (but not soft) to start with, then add any combination of (very) finely chopped veggies. I always use an English cucumber, maybe carrots (blanched), radishes and when tomatoes are in season I add some chopped tomatoes. Also add any or all of the following: toasted nuts of some sort (pine nuts, pepitas, chopped up walnuts or pecans); kalamata olives, crumbled feta or goat cheese or cubed mozzarella, I've added raisins before. Definitely some finely chopped garlic, maybe caramelized onions. For dressing: a few teaspoons of olive oil and red wine vinegar or lemon juice, some oregano, salt, pepper and some fresh chopped herbs like parsley or dill. This makes a great, satisfying lunch and you can make it on Sunday and eat it for a few days. It's also very flexible, like if you have some leftovers like grilled chicken or fish, maybe some cooked veggies just chop them up and add them. It keeps really well because of the vinegar or lemon juice.

Day 2 - Similar to that, I make a pasta salad with my favorite vegetables such as red bell pepper, carrots, celery, artichokes, olives, etc. I sometimes add protein with some ham or chicken and sometimes shave my favorite cheese on top. Then I just make a vinagrette and I drizzle it on top of the salad in the morning. By the time lunch comes around, the dressing has worked it's way down and throughout the salad. With a cooler pack, it can keep until lunch without a refrigerator. It doesn't get soggy either because I don't drown it in dressing.

Day 3 - What about a whole wheat pita stuffed with your favorite veggies? It's one of my favorite healthy foods right now. Or you could do a wrap with a tortilla, just leave off any dressing until you're ready to eat. Day 3 Snack - Fruit would be good too - an apple with peanut butter is so yummy! I bring apples, oranges, and bananas to work all the time.

Day 4 - salads of all sorts (potato, lettuce, rice, couscous)

Day 5 - the hummus idea. My favourite lunch is a selection of cut veggies with a bit of dip (baba ganoush, hummus, tatziki - whatever!), a few olives, some cherry tomatoes, some nuts, and then grazing through them as lunch. If the dip is substantial, like a bean dip is, then you are full throughout the afternoon! Day 5 Snack - cheese sandwich: sharp cheddar, a good sharp grainy mustard, and a nice apple. Granny Smith, Gala, Pink Lady, anything really will do as long as it's fresh and sharp texture.

And mix it up!

apples and peanut butter

Buy a mini cooler. Then your not restricted. I eat cold chilli out of the can all the time. Same with pork and beans. They do sell 12 volt kettles that work in your vehicle. Insulated food containers such as Thermos brand for your hot foods. Preheat them really well though.

place in a zip-lock bag 1 carrot, 1 cucumber, 2 all beef hot dogs, 1-2 pieces of your favorite fruit, and some nuts... and maybe some beef jerky!

lets see.... fruits like apples, oranges, bananas (cept u hate them), should be OK. Nuts (you can buy them in small packages for convenience). Granola bars -- tons of variety these days. Veggies to snack on like sweet or bell peppers and cucumbers should be OK. Peanut Butter sandwich's should hold up just fine. Tuna kits - dont require the refrigerator and they include everything you need down to the tiny spoon and napkin

You could also make warm things at home and use a thermos. Soups, chili, stews, and all that will stay warm for many hours.

Freeze bottles of water the night before -- they will slowly thaw during the day and provide you with cold water all day long.

Hope that helps!

Don't worry about a cooler or heating your food. If you take your food from a fridge at 7am and carry it in an insulated lunch box, it shouldn't go bad by the time you eat it. If you're not leaving it in the hot sun while waiting for lunch it will be fine to eat. (Even if you are leaving it in the sun)

I don't worrry about refrigerating my lunch and it tastes fine at room temp and I've never been made sick by anything I brought from home. You can look at my diary and see what I eat at room temp.
