Prepare produce: dice the onion and orange bell pepper; mince the garlic and jalapeño (remove seeds and ribs if desired); dice the Roma tomatoes; roughly chop the cilantro and remove large stems.
Heat a large skillet over medium-high heat. Add 1–3 tablespoons water or vegetable broth for a no-oil sauté if desired.
Sauté the diced onion and bell pepper for 7–8 minutes, stirring occasionally, until softened and the onion is translucent.
Add the minced garlic, minced jalapeño, and 1 tablespoon taco seasoning to the skillet; stir and cook for about 1 minute until fragrant.
Reduce heat to medium and add the diced tomatoes and crumbled tofu to the skillet; stir to combine and cook, uncovered, for 10 minutes, stirring occasionally.
After 10 minutes, stir in the nutritional yeast, rinsed and drained black beans, and chopped cilantro; cook for 3–4 minutes more until heated through.
Taste and season with salt and pepper if desired. Serve warm with optional toppings such as avocado, guacamole, salsa, pico de gallo, or hot sauce.
