While peppers are cooking, combine goat cheese, milk, lemon juice, lemon pepper, and garlic in a food processor or blender. It should be creamy. If too thick, add a bit more milk. If too thin add a bit more goat cheese.
5 ounces plain goat cheese, 2 tablespoons skim milk, 2 tablespoons lemon juice, 2 teaspoons lemon pepper seasoning, 1 teaspoon minced garlic
