In a large skillet over medium-high heat, brown the ground beef and drain excess fat. Stir in the taco seasoning, chili beans and French-style dressing. Fill the dressing bottle 2/3 full of water and add to the skillet. Bring to a boil, reduce heat and simmer for 15 minutes.

Crush the bag of chips, open the bag, and toss the broken chips into a large bowl with the lettuce, cheese and tomatoes. When the meat mixture is done, combine it with the lettuce, tomatoes, chips and mix well. Then, add salsa and sour cream
