chili
spaghetti sauce. I buy the already made meatballs at the grocery store.
Taco meat.
Stroganoff sauce.
Spanish rice sauce (my own recipe -- ground beef, onion, bell peppers, tomato sauce, spices -- pour over rice. Use lots of tabasco.)
I freeze small containers of spaghetti sauce and use that with frozen meatballs for meatball subs
red beans and rice, except the rice part is later. Just the beans part gets frozen.
butter beans, black eyed peas.

I have cooked hamburger patties in advance and frozen them. That works well. Just heat in microwave.
I have cooked big batches of fried chicken and frozen some of the fried chicken. It is not as good as the first time around but it is very little effort on my part to reheat the chicken in the oven.
I have made fried chicken cutlets, similar to the recipe someone else posted, and frozen them. That turns out well.
I have cooked pork chops and frozen them. Reheat in microwave. They turn out dry.
I have cooked roasts and frozen them in containers with lots of juice from the roast. That turns out well.
I have made homemade tortellini and frozen them. That turns out well.

Enchiladas are great
I also bake a freeze empanadas though we usually use those for lunches (heat well in toaster oven)
Moroccan tangine - heat and serve with couscous cous
Gumbo

These are amazing and really do cook in 15 minutes:

I don’t like frozen food in general, but I like quiche frozen. Some of the Trader Joe’s frozen pasta meals are ok.

I love making all kinds of quiches and freezing them, they always turn out great.
Sauce and meatballs is a staple, one large pot is enough to feed my family of 5 for at least 3-4 meals.
Sloppy Joes, chili, salsa chicken, jalapeno popper chicken, all kinds of soup.

My freezer stash currently includes:

10 meal-size Tupperwares of stuffed shells
About 15 beef empanadas
A quiche
4 pinonos (plantains filled with picadillo cooked in big muffin tins
Plus salmon filets, chicken thighs, mahi mahi filets and crispy shrimp -- all of which can be an easy dinner in about 30 minutes

My standard freezer meals are chicken pot pie filling, chili, meatballs and pasta sauce, pork BBQ, and soups ( chicken and corn chowder, tomato, vegetable beef, and onion soup). Oh, and macaroni and cheese, lasagna, and stuffed shells.

I'm currently strangely obsessed with filling my freezer with delicious homemade meals that just need to be reheated to get through the rest of the winter. Like, I'm fantasizing about doing a week or two of intensive cooking and then never having to cook a full meal until May. This is very new for me as I have always hated any kind of meal planning. So I need ideas. So far I have done a batch of black eyed peas and greens, a ton of ham and navy beans, and sweet potato peanut beef stew. But I can't decide on much outside of the bean/soup/stew family and definitely need variety if I want to make this work. I'm also trying to eat somewhat nutritiously and would like to pack some vegetables/fiber into these meals without having to supplement.

Pretty good cook, no dietary restrictions, and not picky at all. I have a slow cooker, a dutch oven, an instant pot, a sh**ton of snapware, a vacuum sealer.
