1 cup grated Parmesan cheese (I prefer Reggiano but any good quality will do)
1 cup grated Gruyere cheese
1 3/4 cup mayonnaise
2 cups chopped Vidalia onion.
Paprika
Preheat oven to 350°F
Mixed together 1st 4 ingredients, place in a small baking dish and sprinkle with paprika
(just to give it a nice color) and bake for 25-30 minutes until bubbly. Serve with your
favorite cracker.
