01 - Heat 1 tablespoon olive oil in a large skillet over medium heat. Add diced potatoes and cook, stirring occasionally, until golden and tender, about 10-12 minutes.
02 - Stir in the chopped onion and jalapeño. Cook until softened, about 3 minutes. Season with salt and black pepper. Transfer the mixture to a plate and keep warm.
03 - In a bowl, whisk eggs with milk, salt, and black pepper.
04 - In the same skillet, heat remaining olive oil over medium-low heat. Pour in eggs and scramble gently, stirring with a spatula until just set.
05 - Add the cooked potato mixture back to the skillet with eggs and sprinkle in cheese. Stir until cheese is melted and everything is combined. Remove from heat.
06 - Warm the tortillas in a dry skillet or microwave until flexible.
07 - Divide the potato-egg-cheese filling among the tortillas. Top with fresh cilantro and serve with salsa.
