Preheat oven to 375 F.
To a food processor, add you extra firm tofu. Add nutritional yeast, turmeric powder, black salt, onion powder, garlic powder, and black pepper to the crumbled tofu. Blend until smooth.
In a skillet, heat olive oil over medium heat. Add the finely chopped vegetables and sauté until they are slightly tender to your liking. Season with salt to taste
Combine the sautéed vegetables with the seasoned tofu mixture in a large bowl. Mix until well incorporated. If using vegan cheese, fold it into the tofu and vegetable mixture.
Grease a muffin tin or line it with paper liners. Spoon the tofu and vegetable mixture into each muffin cup, pressing it down slightly.
Bake in the preheated oven for 20-25 minutes or until the tops are golden brown.
Remove from the oven and let the muffins cool for a few minutes. Garnish with fresh herbs, such as chives or parsley. Serve warm and enjoy!
