How often do you cook? Have the same few things in rotation? Cook for anyone else too? Prep multiple days at a time or cook every day? I personally work a weird schedule so I prep food 5 days at a time. Also only eat one big meal a day. That could be anything in my dozenish meals rotation. I prep for my girlfriend too but shes simple. For her I cut up some vegetables (bell peppers, cauliflower, celery and carrots usually) then cook up a couple pounds of seasoned meat (chicken breast or 90/10 ground beef). What about you?
Kept it simple, a drizzle of olive oil and balsamic vinegar over the veg, apple cider vinegar on the cheap steak. Salt and pepper over the lot of it. Veg goes on the grill a while before the steak. Fed me 4 meals with some spaghetti on the side.
