Some easy to make meals in my diet:

Tuna mashed in peanut butter + mayo, rice, tomatoes. Sounds gross, but it's pretty good!
~ 30g protein, 70g carbs, 15g fat = ~540 cals



Basic oven roasted chicken drumsticks with olive oil.
~ 15g protein, 6-10g of fat = ~150 cals per drumstick



3 slices of bread, 4 scrambled eggs. Portable food!
~24g protein, 40g carbs, 24g fat = ~ 430 cals


So far consistent with 5 meals a day, supper usually just peanut butter and tuna/milk.
