Pre-Heat oven to 475 degrees.

Separate 1 egg (this is the egg yolk extractor I use ... http://www.yolkbgone.com/ ); set the yolk aside. Whisk the egg white, chili powder and 1/2 teaspoon salt in a large bowl until frothy. Add the potatoes, onion and poblano; toss. Coat a baking sheet with cooking spray; spread out the vegetables, then coat with more cooking spray. Bake, flipping once, until golden brown, 25 to 30 minutes.

Toss the tomatoes, 2 tablespoons cilantro and 1 tablespoon hot sauce in a bowl; season with salt and set aside.

Whisk the reserved egg yolk and 7 eggs with 1/4 cup cilantro and 1/2 teaspoon salt in a bowl until frothy. Melt the butter in a medium nonstick skillet over medium heat; swirl to coat. Add the egg mixture and cook, stirring, until just set, about 5 minutes.

Toast the tortillas in a dry skillet or wrap in a damp paper towel and warm in the microwave. Toss the remaining 2 tablespoons cilantro and 1 tablespoon hot sauce with the vegetable mixture

Divide the vegetables and scrambled eggs among the tortillas. Serve with the tomato salsa.
