Cheddar Onion Dip

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!
