PREPARATION:
- Place sliced meat in a large resealable bag. Add 2 tablespoons lime juice, oil, chili powder and garlic powder. Close bag securely; turn to coat. Marinate in refrigerator at least 30 minutes or up to 8 hours.
- Preheat oven to 350°F. Arrange tortilla strips on a nonstick baking sheet and spray tops of strips lightly with nonstick cooking spray. Bake for 6 to 8 minutes or until tortillas are crispy; set aside.
- In a small bowl, stir together tomatoes, green onions, cilantro, and black olives; set aside. Spray a large nonstick skillet with nonstick cooking spray. Heat skillet over medium-high heat, add beef and cook for 6 to 8 minutes or until meat is cooked through, stirring occasionally; set aside. (Beef may have to be cooked in batches.)
- To assemble salad, arrange endive on a large platter. Scatter the red bell pepper and green beans over lettuce. Mound cooked beef in the middle of the salad. Top with tomato-olive mixture. Sprinkle tortillas strips on top.
- To make dressing, place buttermilk, avocado and 2 tablespoons lime juice in a blender and process for 15 to 20 seconds until mixture is smooth. Drizzle dressing over salad or serve on the side.
