Brown ground beef and drain. Add taco seasoning - follow package directions. Alow to cool slightly or put in refrigerator if you don't want to use the salad right away.
TEAR lettuce into bite size pieces, but into bowl. Cut tomatoes in half, and spread out on top of lettuce. Put cheese on top of tomatoes. Cover and chill until ready to serve. Just before serving, add Doritos, meat (if refrigerated, use microwave to take chill off of meat), and salad dressing. Toss well!
Don't skimp on the cheese or doritos, the more the better! I use the whole bag of Dorito's. Not snack size, or Extra large, just the regular size bag -- .
