Heat the avocado oil in a non-stick skillet over medium-high heat until shimmering.
Add the ground turkey, diced red bell peppers, and onions to the pan, breaking the meat apart with a spatula until browned and the vegetables are tender.
Season the turkey mixture with sea salt and black pepper, then remove from the pan and set aside in a warm bowl.
In a small bowl, whisk the whole egg and egg whites together until well combined and slightly frothy.
Lower the skillet heat to medium and pour in the egg mixture, stirring gently with a silicone spatula until the eggs are fluffy and just set.
Warm the whole wheat tortilla in a separate dry pan or directly over a low gas flame for 30 seconds until soft and pliable.
Assemble the burrito by spreading the black beans in the center of the tortilla, followed by the sautéed turkey mixture and the scrambled eggs.
Top with the fresh salsa fresca, fold in the sides of the tortilla, and roll it up tightly before serving warm.
