Combine the picante sauce, mayonnaise, salt, and pepper in a medium bowl.
Mix well and set aside.
Salad
Sauté the onion and ground beef in a skillet over medium heat until the beef is browned. Drain.
Add the kidney beans, mix well, and set aside to cool.
When ready to serve, place the chopped lettuce in a large bowl.
Add the beef mixture, tomatoes, cheese, and Doritos.
Pour the picante dressing over the salad along with a small amount of Catalina dressing and mix well. Alternatively, you can serve the Catalina dressing on the side.
Recipe Tips
I do not add the Catalina Dressing to my other dressing as not everyone likes it. Also, do not add the chips until ready to serve.
