Amanda's Cheddar Cheese Ball

1/2 lb grated sharp cheddar cheese

4 oz cream cheese, room temperature

1/4 cup mayonaisse

1/8 teaspoon onion salt

1/8 teaspoon garlic salt

1/4 cup chopped walnuts, plus enough to roll and cover the cheese ball.

Put all ingredients (except the nuts to roll the cheese ball in) in food processor, process until well combined.  (Amanda actually mixes this by hand, wearing plastic gloves to keep clean.)  Put nuts to roll the ball in a pie plate.  Pile the cheese mixture on top of the nuts (in as close to ball shape as you can get it).  Bring the nuts up the sides and on top as best you can, then pick up the ball and roll it around in the nuts to cover completely.  Refrigerate for at least an hour before serving.
