Place a medium non-stick skillet over medium-high heat and add the avocado oil.
Add the diced yellow onion and red bell pepper to the skillet, sautéing for 3-4 minutes until the onions are translucent and the peppers are tender.
Add the ground turkey chorizo to the pan, breaking it up with a spatula, and cook until browned and fully cooked through, about 5-6 minutes.
In a small bowl, whisk together the whole egg, egg whites, sea salt, and black pepper until well combined.
Lower the heat to medium and pour the egg mixture over the chorizo and vegetables, stirring gently until the eggs are soft-scrambled and just set.
Remove the mixture from the heat and stir in the fresh cilantro.
Warm the whole wheat tortilla in a separate dry pan or microwave for 15 seconds until pliable.
Spoon the chorizo and egg filling into the center of the tortilla, fold in the sides, and roll tightly into a burrito.
Place the assembled burrito back into the hot skillet, seam-side down, and toast for 1-2 minutes per side until the exterior is golden and crispy.
