1/2 cup cup shredded low fat cheddar cheese(about 2 oz.)
Preheat oven to 400°. Arrange tortilla strips on baking sheet. Bake, stirring twice, until crisp, about 10 minutes. Reserve handful of tortillas for garnish.
Meanwhile, brown ground beef with 1/4 teaspoon chile powder in 12-inch nonstick skillet over medium-high heat. Remove skillet from heat, then stir in beans and 1/4 cup Wish-Bone® Ranch Dressing; set aside to cool.
Layer 3 cups lettuce, 1/3 of the tomato and onion and 1/2 of the beef mixture in trifle dish or deep glass bowl. Sprinkle with 1/2 of the tortilla strips and 1/2 of the cheese; repeat layers. Top with remaining 2 cups lettuce, remaining tomatoes, onion and cheese. Sprinkle with reserved tortilla strips.
Combine remaining 1/4 teaspoon chile powder with remaining 1/4 cup Dressing and serve with salad.
