Gather your ingredients so that you have everything close at hand on the counter or table.
Prepare the Ingredients
Using a sharp knife and cutting board, dice the 1/2 cup sweet onion.
Slice 2 medium ripe avocados in half and remove the seed and peel. Cut into small chunks.
Dice 1 medium Roma tomato.
Make the Dip
Using a blender or immersion blender, place the chopped avocados, diced onion, 4 oz chopped medium green chilies, 2 tablespoons lemon juice, 1 tablespoon minced garlic, 2 teaspoons hot sauce, 1/2 teaspoons kosher salt and 1/2 teaspoon freshly ground black pepper in a container. Blend until ingredients are mashed to desired consistency. (If you prefer a chunkier dip, you may use a potato masher for this.)
Fold the prepared diced tomato into the avocado mixture. This step is optional. If you'd prefer the dip without tomatoes, simply omit this step.
Spoon the dip into a pretty serving bowl. Serve immediately or cover and refrigerate until ready to serve. Serve with corn tortilla chips or on your favorite Mexican dish. Makes 1 1/2 cups.
