I typically spend the week thinking about what I’ll make for main meals and then execute it all on one day. I make 8 full meals then 5 overnight chia oats and 3-5 portions of whatever meat was on sale at the store. It typically takes a few hours on my last day off any week (work a really weird schedule). I supplement any other cooking/more oats as the week progresses.
I’ve prepped grapeleaves as a side for my meal once. I make them the way my grandma taught me, vegetarian with rice and a ton of lemon juice. I’ll definitely look into the things you talked about more!
