Onion Dip

Just in time for Super Bowl (how does that translate to Spanish??)... This is our favorite appetizer to take to dinner parties and get-togethers.

1 cup mayonnaise
1 cup sour cream
2 cups chopped sweet onion (vidalias work great)
1 cup shredded cheddar cheese
Mix all ingredients together and place in a shallow dish (9x9 works fine). Sprinkle top with Parmesan cheese. Bake at 375 until bubbly and golden brown on the top. Serve with crackers or pita chips.
