Preheat oven to 375°F (190°C). Toss tortillas with 2 tbsp (30 mL) oil until coated. Transfer to two parchment paper–lined baking sheets; bake on top and bottom racks of oven, switching and rotating trays halfway through, for 8 to 10 minutes or until crisp and browned around edges.
Heat remaining oil in large skillet set over medium-high heat; cook onion, red pepper, jalapeño, garlic, and half of the salt and pepper for about 5 minutes or until vegetables start to soften.
Meanwhile, whisk together eggs, 2 tbsp (30 mL) water and remaining salt and pepper. Pour egg mixture into skillet; cook, stirring frequently, for 1 to 2 minutes or until soft curds start to form. Stir in tortilla chips and tomato; cook, stirring, for about 5 minutes or until eggs are set. Sprinkle with cheese and cilantro.
Notes
Serve with hot sauce, sour cream, tomato or tomatillo salsa.
Alternatively, instead of crisping the tortillas, use lightly salted corn tortilla chips.
