buy 7 meal prep tupperware things on amazon. Its really light microwave and dish washer safe.
youtube: body building tuna bake/casserole; ground beef and veggie saute; lean/wheat pasta. or whatever sounds good/wanna try/sounds healthy/etc...
premake these in bulk and put in container and refrigerate. (i only make 7 days worth because every sunday or day off, I grocery shop and cook)
before you go to work, get those tupperwares out and pack the portions. put in a ice lunch box thingy or backpack if u have to carry it with you all day.
eat them cold. not too bad. If you don't need to eat every 2-3 hours. bring like two of those dishes instead of 3 or 4. also almonds and string cheese and fruit are nice healthy snacks.
here's personally what i do:
cut:
1st meal: same thing as u. prepped at home.
2nd meal pack: chicken breast 6oz (bought raw and cooked in bulk and all chicken put into ziplock or glass tupperware (if its not being used) with spring greens, olive oil, balsamic vinegar (NOT VINGERETTE OR SAUCE)
3rd meal pack: ground beef sauted with veggies of choice
4th meal pack: black beans S&W 50% sodium in a can. (only because the ingredients are beans water and salt - so can is ok here for me) 6oz chicken from my bulk reserves explained above, and raw veggies cut into eatable pieces
5th meal and 6th meal: eat at home
bulk: 1st meal. same with more eggs and oatmeal
2nd-6th meal: brown rice, 6oz chicken, veggies
PWO: protein shake
