Preheat oven to 425°F. Line a rimmed baking sheet with foil, spray with cooking spray, then set aside.
Chop pepper and cilantro; heat oil in a nonstick skillet over medium heat.
Crack eggs into a large mixing bowl; whisk in sour cream, garlic powder, salt, and pepper, then add to the hot skillet.
Using a rubber spatula, gently scrape the bottom of the pan and fold eggs over to scramble. Remove from the heat when still slightly under-cooked.
Gently fold cheese, peppers, cilantro, and salsa into the eggs. Microwave the tortillas until warm and pliable.
Place about 1/4 cup egg mixture into the center of each tortilla, roll up tightly, then place on the baking sheet seam-side down, leaving a bit of space between each one.
Lightly spray the tops with cooking spray and bake for 15 minutes or until edges are golden brown and crisp.
Serve with tangerines on the side.
