Mexican Stuffed Bell Peppers - stuffed with ground beef, black beans, rice, tomatoes, spiced just right with Mexican spices, topped with grated Cheddar and Mozzarella cheese. Baked in a meatless tomato sauce (right from the jar).
Stuff each bell pepper with the filling. Fill the baking dish with marinara spaghetti sauce and up to 2/3 cups of water (don't pour all water at once - just pour enough to make the marinara sauce less dense). Place stuffed bell peppers tightly into prepared baking dish, cavity side up. In my case, I used 2 large bread pans. Top each pepper with both shredded Mozzarella and Cheddar cheese. Sprinkle some cheese over the tomato sauce too. Cover with foil
Bake stuffed bell peppers for 30-40 minutes, until the peppers are tender and the filling is hot. Serve in shallow bowls, with some of tomato sauce on the bottom.
