Step 1

Preheat your oven to 350F (180C).  Line with parchment paper or lightly grease a large baking sheet.

Step 2

Mix the nutritional yeast, soy sauce, olive oil chili powder, garlic powder, and liquid smoke together in a large bowl. It will make a brown paste-like texture.

Step 3

Crumble the block of tofu with your fingers into the bowl along with the seasoning. Mix the tofu crumbles with the seasoning making sure all of the tofu is evenly coated. Spread the tofu crumbles evenly over the pan. Bake for 35 to 45 minutes, stopping to stir the tofu every now and then. Keep a close eye on it towards the end so that it doesn't burn. You want the tofu to be nice and browned. The smaller crumbles will be darker than the larger crumbles, and that's ok because it will provide a variety of texture.

Step 4

In the meantime heat the tomato sauce, and cook pasta according to package directions. Stir the tofu into the sauce, and heat through. If you find the sauce is too thick, stir in a bit of water until desired consistency is reached. Serve over hot pasta with a sprinkle of Parmegan.
