This is the most wonderful sauce to serve with buttered new potatoes, everyone will love it. Unless you are having a party you might want to cut this in half.
Makes about 3 cups
3/4 cup mayonnaise
1/4 cup sour cream
2 cups finely chopped yellow onions
Salt and Pepper
In a glass dish, stir everything together. Check salt and pepper. Cover and refrigerate until serving time. How hard is that.
