Cut the corn tortillas into triangles and arrange on a baking sheet in a single layer.
Bake at 350° for 9-10 minutes or until browned and crisp to make oil-free corn chips.
Use a fork to crumble the tofu.
In a small bowl, stir together the onion powder, salt, garlic powder, chili powder and cumin with enough water to thin the spices so it’s pourable.
Set the tofu and bowl of spices aside.
In a skillet over medium heat, cook the onion and bell pepper for several minutes.
Stir often and add a little water if it begins to stick.
Once the onion has softened, add the jalapeno and tomatoes and cook a couple more minutes.
Scoot the vegetables to one side of the skillet and put the tofu in the other half.
Drizzle the spices over the tofu, stirring to combine.
Stir the veggies and tofu together in the skillet and continue to cook until the tofu is hot.
Crumble the corn chips into the tofu, stirring to distribute the chips in the tofu.
Sprinkle with cilantro if desired.
