What are your 5 essential foods in healthy eating?

I buy food for the week every Sunday night or early Monday morning and take to work with me. My list is:

Greek yogurt (I try different types)
oatmeal
cottage cheese
spinach and salad greens, cucumber
celery
Hummus
raw broccoli and carrots (go in salad)
cherry tomatoes
mushrooms
strawberries, plums, blueberries, oranges
sara lee 45 calorie multigrain bread
sargento ultra thin cheese slices
deli turkey, deli ham
a whole rotisserie chicken
tuna packets

I make a huge salad and top it with chicken 3 out of the 5 days for lunch. Sometimes I'll make a sandwich with the deli meat, add veggies and cheese on the 45 calorie bread. I top my salad with tuna some days. I make steel cut oatmeal and add protein powder to it. I dip celery sticks in hummus for a snack or add cherry tomatoes and pepper to half a cup of cottage cheese.

I also have a complete measuring spoon and cup set and a food scale at work.

For dinner - I make wild caught salmon with either scallops or shrimp in the oven, with lime juice and fresh garlic and onion. I add a veggie - asparagus, broccoli, brussel sprouts, etc. Other times I'll have grilled chicken, or shrimp, or a small steak with a veggie, and occasionally add a sweet potato.

I think I just found my food hero! This is so similar to what we eat, but I never thought about bringing a measuring spoon, scale, etc. to work. Do your co-workers ever give you a hard time for taking up all the fridge space? Luckily we have two fridges at work, but they do fill up pretty quickly during the week. Love your post, though! I'm printing this for my next trip to Earth Fare (my favorite local grocer).

Thanks!
