My Aunt had this when I was there over the weekend. She says that it is like Chile's Southwestern Salad. I don't know if it is or not, I just know that it is good.
Start with your lettuce of choice, mine is Romaine. Drain and rinse a can of black beans and corn. Chop some onion if you like it, I prefer to leave it out. Add these to the salad and mix well. Top with Balsamic Vinegar Dressing and Ranch, equal parts. Mix until dressings are combined and enjoy!
