Combine sour cream and 2 oz of parmesan cheese (reserve other ounce for topping later) in a 2qt casserole dish. Stir in spinach and artichokes. Mix well. Cover top with monterey jack and other ounce of parmesan cheese.
Bake for 15 minutes at 400~ and then broil for about 5 minutes or until cheese is golden brown. Serve with tortilla chips and side dishes of sour cream and your favorite salsa. This makes about 4 times what you are served at a restaurant so you may want to adjust the ingredients.
