This is another one that my mom and grandmother have been making for as long as I can recall. My grandmother makes it every Christmas eve. My husband, who HATES mayonaise, thinks this is the best thing ever created. And I have to say, he might be right!
1 cup mayo 1 cup cheddar cheese 1 cup chopped onion 1/2 tsp garlic powder
Mix together and place in baking dish. Bake at 350 until bubbly. Serve with Cracker and Fritos!
