PREPARATION:
- Preheat oven to 375°F. If desired, combine avocado, yogurt and lemon juice in food processor or blender; process until smooth. Set aside.
- Place tortillas in single layer on center rack of oven. Bake 5 minutes or until crisp and golden, turning halfway through baking. Set aside.
- Spray large skillet with cooking spray and heat over medium heat. Add onion; cook and stir 10 minutes or until onion begins to brown. Add chili powder and oregano; cook and stir 1 minute. Remove from heat; stir in beans and 1/4 cup water. Mash beans with fork until smooth; if necessary, add more water, 1 tablespoon at a time. Return to heat. Cover and cook, stirring occasionally, 6 minutes or until heated through.
- Place each tortilla on plate. Spread 1/3 cup bean mixture over each tortilla. Top with 1 cup lettuce, 1/4 cup cheese, 1/4 cup salsa and about 2 teaspoons olives. Garnish with avocado mixture in cherry tomato cup, if desired.
