Place the onion, peppers, and potatoes on the baking sheet. Drizzle with oil and season with chili powder, garlic, smoked paprika, onion, salt and pepper.
Combine everything together until all ingredients are well coated. Evenly spread in one layer.
Bake for 20-30 minutes until potatoes are cooked through. Stir every 10 minutes for even cooking. *If you would like to crisp them slightly, broil them the last 5 minutes. Keep a close eye on them to prevent burning. Taste for seasoning and add more if needed. Serve immediately.
Topping ideas: fresh-cut parsley, cilantro, lime juice, crushed red pepper, hot sauce, salsa, or vegan sour cream.Serve with Tofu Scramble and Vegan Bacon for a hearty vegan breakfast. I used Yukon Gold Potatoes, but any variety will work.
