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?
Cook 4-12 portions of something freezable (big pan!) most weekends, eat a portion, freeze the rest.
Cook something simple 2 days a week (burgers/fajitas etc)
I now have a selection of 5 or 6 different frozen meals in the freezer at a time. Most just need rice, pasta or potato added.
I do the same thing pretty often.
