Mississippi Sin Dip

This is a delicious appetizer. Everytime our family goes to the beach house in the summer I make this and it's gone in a flash.

1 (16 ounce) container sour cream
1 (8 ounce) package cream cheese, softened
1 pkg. bacon, cooked, drained and crumbled (or use pre-cooked)
1 cup shredded mild cheddar cheese
1 (16 ounce) pkg. cubed ham (any ham lunch meat, cut in cubes)
1 (4 ounce) can green chilies, drained
1/2 cup finely chopped sweet onion

Preheat oven to 350. Mix all ingredients well and pour into a lightly greased 10 x 8 inch baking dish. Bake for 30-45 minutes. Serve with Ritz crackers. Refrigerate leftovers (but don't expect any).
