My Mom makes this and it's really good as a main dish too!
Layer the following:
1 head lettuce
Chopped green onions
1 lg can ranch style beans (washed)
1 pkg (small) fritos (crushed) OR Doritos (I really like doritos)
1 pkg. longhorn Colby cheese – grated
Before serving, pour 1 bottle Kraft Catalina dressing and toss. (I use much less)
