I some times cook several meals for the week, just so I can free up some time during the week. The kitchen shuts down for everything else but I find that I waste less food that way. In my case a lot of time I just use half of a veggie, save the other half, which i then forget about until I find it in the back of the fridge... buts thats neither here or there.
I get stew meat and throw it in the crock pot with onions, spices, bone broth maybe peppers and turn it on high. While that cooks I can cut up chicken pieces and sautee them in cast iron pan salt and pepper until browned then I add half a can of coconut milk and curry powder, cover, turn to super low heat and simmer for as long as im in the kitchen. In the meant time I am also roasting something in the oven, salmon or perhaps some churrasco steak or both. Each dish can be split in 2 meals. I also have 2 crockpots so some times they are both on duty.
I live in a tiny apartment with the worlds most horrible designed kitchen in terms of space, but it is totally doable!
