I pulled out this recipe from my friend Kim. It is simple, but has great flavor. The tangy artichokes and mayo pair well with the creamy mozzarella and the sharp parmesan.
Artichoke Cheese Dip
1 c. parmesan cheese
1 c. mayo
1 can artichoke hearts, quarters or halves, finely chopped
3 c. mozzarella
Mix together, flatten in a greased casserole dish. Cook at 350 for 40-45 minutes. Best with a buttery cracker like Ritz.
