I make batches of pasta sauce and freeze portions in freezer bags - sometimes I even mix it with pasta and then freeze. Then its just heat and serve.
I also pre-make beans and rice - I cook dry red kidney beans (takes 2 hours) with water, a fried onion, and a can of tomatoe paste. I add water here and there so it's soupy. Then I mix that with white rice and freeze it. You can eat it alone with sour cream and hot sauce, or on tortillas as burritoes.
You can also do hard boiled egg, avocado, and onion burritos.
Or fry chicken tenderloins in olive oil for 15 minutes - season with garlic powder, tumeric, and a hint of cinnamon. It's yellow/persian ish. Serve with frozen veggies.
