Yes, you can. You can easily stir fry a veggie blend of chopped bell peppers, diced white or red onion, sweet corn and even cut up zucchini. Then add a layer of the vegetable blend on top of the ground meat mixture before topping it with the shredded cheese. Additionally you can also add some whole beans such as black beans, pinto beans or kidney beans. Finally you can sprinkle the baked dish with sliced black olives alongside the fresh tomatoes and cilantro.
