Press tofu in paper towels under a heavy pan for 15 minutes.
Make salsa: Combine tomatoes, red onion, bell pepper, lime juice, cilantro, oil, salt, and pepper. Set aside.
Heat oil in skillet over medium. Crumble tofu into the pan. Cook 3 minutes. Add nutritional yeast, black salt, garlic powder, cumin, salt, and pepper. Cook another 3–5 minutes.
Stuff sweet potatoes with scramble, black beans, and salsa. Top with avocado and sour cream if desired.
Notes
For extra eggy flavor, add a tiny pinch of black salt at the very end. Pinto beans work as a swap for black beans.
