Add the peppers, onion, garlic, and jalapeno pepper to the pan and saute with a bit of water until softened (again, oil is optional). Chop the tofu slices into small bits and add to the pan along with the salsa, tomato paste, 1/2 cup water, and seasonings. Add a bit more water as needed until the mixture is evenly mixed. Simmer for about 10 minutes until fully heated through and the liquid is absorbed.
