Steps

1. Add the avocado, tomato, sliced scallions, corn, chiles, oil and lime juice to a medium bowl and toss lightly to mix. Add salt and pepper to taste.
2. Heat a non-stick pan over medium-high heat. Place one tortilla on the pan to warm, and then turn it over. Sprinkle with some of the grated cheese and chopped scallions and fold in half. Continue to heat until the cheese has melted. Remove to a cutting board and cut into triangles. Hold warm while you repeat with the remaining tortillas.
3. Serve quesadillas hot with the avocado salsa.
