I was in a similar situation to yours years ago. Got home late and didn't want to spend a lot of time in the kitchen cooking.
I managed with a combination quick cook meals and with cooking large quantities on the weekend and freezing the food in meal-sized packages. Think chili, soups, stews, lasagna, pasta sauce (with or without meatballs or sausages), enchiladas, etc.
For quick meals, I always had a supply of frozen meats in meal-sized portions - chicken breasts, pre-made burgers, chops, etc. Take a meat out of the freezer the night before and it's ready to go the next night when you get home. Then you can grill, broil, pan fry or bake it quickly.
Sides are easy too. With a combination of the microwave and toaster oven, you can have baked potatoes in 30 minutes. While they are cooking you can be cooking the protein and a veggie.
