Prep the veggies: Finely mince the red onion. Core the peppers and cut them into small dice.
Tempeh: Heat a large pan with olive oil. Crumble the tempeh into the pan and sauté over medium-high heat for 5 minutes, stirring regularly. Once golden, remove the tempeh from the pan.
Sauté the peppers: Add another drizzle of oil into the pan. Add in the onion, peppers, and season with salt, cumin, paprika, and garlic powder. Sauté for 10 minutes over medium heat until soft.
Combine: Add the tempeh back into the pan with the drained and rinsed corn. Sauté for another minute.
Make the burrito: Add a few tablespoons of the mixture at the center of a burrito. Top with avocado dice and optionally drizzle with salsa. Fold the edges over and roll the burrito.
Fry the burrito: If needed, add another splash or oil to the pan. Fry the burrito over medium heat for 1 minute on each side until golden.
