Finely dice the red bell pepper and yellow onion.
Heat the avocado oil in a non-stick skillet over medium-high heat.
Add the diced peppers and onions to the skillet, sautéing for 3-4 minutes until softened.
Add the ground turkey chorizo to the pan, breaking it up with a spatula, and cook until browned and slightly crispy.
Stir in the black beans and cook for 1 minute until warmed through.
In a small bowl, whisk together the whole egg and egg whites with sea salt and black pepper.
Lower the heat to medium and pour the egg mixture into the skillet with the chorizo and vegetables.
Gently scramble the eggs until just set and fully incorporated with the other ingredients.
Warm the whole wheat tortilla in a separate dry pan or microwave for 15 seconds.
Place the egg and chorizo mixture in the center of the tortilla, fold in the sides, and roll tightly.
Optional: Place the rolled burrito back in the hot skillet for 30 seconds per side to seal the seam and add a golden crunch.
