Cheesy Garlic Bread

1 small loaf French bread, split or sliced

1 and 1/2 Tablespoons butter

4 cloves garlic (minced)

3/4 cup mayonnaise
1/3 cup sweet onion, finely diced
3/4 cup grated cheddar cheese 

1/3 cup mozzarella

1/4 cup grated Parmesan cheese

dash of pepper

dash of onion salt
generous teaspoon dried parsley
 3 to 4 Tablespoons cream (enough to make spreadable but still thick)

Directions:

Mix everything but the bread,  butter, garlic and onion in a bowl.

Melt butter in big cast iron skillet, saute garlic and onion until softened and golden.  Remove. Place sliced french bread in pan and heat just until the bottom is a little toasty but not browning.

Spread cheese mixture on bread and put under the broiler 4-6 minutes until bubbly and the edges are golden brown.
