No one we know can resist 7 Layer Dip. It's seven layers of delicious. Many recipes start with a layer of mashed or refried beans topped with guacamole, chopped black olives, sliced green onions, chopped fresh tomatoes, sour cream and grated cheddar cheese. Serve your dip with tortilla chips and consider substituting layers with your favorite ingredients such as spicy jalapenos, salsa, or cooked crumbled chorizo sausage.
