I'm raiding my mom's recipe box today. Here is a taco dip that whenever she makes it for a party, I make her make extra for me to eat!
16 ounces sour cream
8 ounces cream cheese, softened
Small package taco seasoning
Green peppers, diced
Mix the sour cream, cream cheese and taco seasoning. Spread on a 9x13" pan. Top with lettuce, cheese, tomato, green pepper, black olives, onions (basically whatever you like on your tacos). Enjoy with tortilla chips!
