This sounds ridiculous so I just had to try it. Plus it's only 5 Weight Watchers points, not that I know what that really means, but I figured it was safe and healthy! This recipe makes a ton, so scale it back for your needs.
adapted from Culinary Hill
1 lb ground beef
1 package taco seasoning
1/4 cup water
1 bag of butter leaf lettuce
1 large tomato, diced
1 large green bell pepper, diced
2 cups shredded cheddar
1/2 bag Nacho Cheese Doritos, crushed
French salad dressing (if you like - I used sour cream instead of dressing)
In a medium skillet over medium-high heat, brown ground beef; drain well. Stir in taco seasoning and water; simmer until thickened. Remove from heat. In a very large bowl, combine lettuce, tomato and pepper. Add cheese and beef mixture and stir. Right before serving, add Doritos and toss to combine.
