Carolyn says: "Using tongs, hold each tortilla over a gas flame 10 to 20 seconds on each side or until charred. It makes a tremendous difference in flavor."
Whisk together eggs, egg whites, green chiles, cream cheese, pepper, and salt. Heat olive oil in a large nonstick skillet; add egg mixture, and scramble. Divide egg mixture among tortillas. Top each with 1 Tbsp. chopped green onions and hot sauce to taste. Roll up each tortilla, and serve immediately.

A flour tortilla makes it a burrito not a taco (corn tortilla for tacos). But even with a corn tortilla a good solid recipe.
