Fry diced potato in oil first. When potato is almost done, add onion, bell pepper, crumbled tofu, and remaining spices (Except nutritional yeast). I really like chipotle powder, but if its not available or you don't like it, you can use cayenne powder, or omit that step all together.
When it is all cooked, then I stir in the nutritional yeast - howe'ver much you prefer- to give it a cheezy egg taste. sometimes I also add a little soy margarine in this step for added flavor.
Sometimes I use Fantastic Foods Tofu Scramble with this recipe. But when I don't have any on hand, I make it from scratch. You can vary this recipe in so many ways to suit your taste. Its really wonderful.
I hope you try it, and experiment with your own ingredients. Its great for any meal of the day.
