Preheat oven to 350°.
Combine all ingredients except 1/2 cup of cheddar cheese. Spoon into a 2-quart casserole, then top with remaining 1/2 cup of cheese.
Bake for 35 minutes or until dip is hot. Dip, dip hooray!
Spanakopita Dip: Substitute feta cheese for the cheddar and omit artichoke hearts. Spoon into mini phyllo cups and bake 8 minutes or until filling puffs.
