Place a non-stick skillet over medium-high heat and add the olive oil.
Add the ground turkey, diced onion, and diced bell pepper to the pan, breaking the meat into small crumbles with a spatula.
Cook until the turkey is browned and the vegetables have softened, approximately 5-7 minutes.
Season the mixture with sea salt, black pepper, and garlic powder, stirring well to combine.
Reduce the heat to medium, pour in the egg whites, and add the baby spinach.
Stir the mixture constantly until the egg whites are fully set and the spinach has wilted into the scramble.
Warm the whole wheat tortilla in a separate dry skillet or microwave for 15 seconds until soft and pliable.
Spoon the turkey and egg mixture into the center of the tortilla, top with the chunky salsa, and roll tightly into a burrito.
