freeze meat in small portions. We are a couple but use the microwave or grill mostly. I cook pasta in the microwave in a pasta cooker. I just found Prego spaghetti sauce with mini-meatballs. Easy dinner with salad.
I use Uncle Ben's Redi Rice, Just heat. Add to hamburger and a can of tomatoes, season to make Spanish Rice or cream of mushroom soup. I buy chicken strips, brown and add yellow rice (they make small packages). Top with black beans. Stouffers makes lasagna and other things in small packages in the freezer section that are microwavable. We like the meat loaf and add a package of instant mashed potatoes and can of green beans or peas. Pizza that you can cook in microwave. In the winter, chili and chicken vegetable soup in one pot. Look for the microwavable macaroni and cheese one serving.
