Step 1Combine tomatoes, onion, mango, jalapeno, garlic, lemon juice, oregano and salt in small bowl. Let stand 30 minutes for flavors to develop.
Step 2Heat tortillas, one at a time, on top of open gas burner, turning with tongs until tortilla is toasted on both sides, 30 seconds to 1 minute per side. Top each hot tortilla with 1 tablespoon Teleme cheese, spreading slightly. Spoon 1 tablespoon mango salsa over cheese and top with cilantro sprig.
