Heat the olive oil in a medium nonstick skillet over medium heat. Add the onion, tomato, jalapeño, garlic, salt, and several grinds of pepper. Cook for 2 minutes, stirring, or until softened. Add the eggs and crumbled chips and stir to scramble. Stir in the cheese and remove from the heat. Season to taste.

Divide the migas between two plates and sprinkle with the cilantro. Serve with the tortillas, avocado slices, lime wedges, and salsa.
