Heat 1 TB of oil in a large skillet. Add the onions, mushrooms, and pepper until cooked (about 5-8 mins).
Crumple the tofu into pan, add spices, and a little water/veggie broth when necessary so nothing sticks to the bottom. Cook until heated through (about 3-5 mins).
Once tofu is heated, add spinach and heat through.
