Preheat oven broiler to high.
Under the broiler, toast English muffin halves on a baking sheet until golden brown. Remove from oven.
Top each muffin half with sliced avocados and sliced tomatoes; lightly salt the tomatoes.
Sprinkle chopped basil leaves over the tomatoes. Put a layer of mozzarella cheese over the basil, sprinkle with grated Parmesan cheese, and top with black pepper.
Broil prepared muffin halves for approximately 2 to 3 minutes or until cheese has melted. Remove from oven and enjoy!
Makes 4 servings.
* You could also use bagels instead of English muffins.
