This is a regular weeknight dinner for me and my family, and a wonderful way to clean out the refrigerator. I make it a little different each time, but I always sauté ground beef or ground chicken and add whatever tomatoes I have on hand, and vegetables starting to go. Sauté in any assortment you like, but mine always includes onion and garlic, and add any other seasonal favorites like zucchini and mushrooms. Top with a tomato sauce and bake in the oven. If you are doing a grain free diet, it’s great just like this, but is also nice to add rice and top with a bit of parmesan. For vegans double up on the vegetables and onions.
