Turn heat to low and add Spinach and cheeses. Mix together. Cheeses will melt as they heat. You can place a lid on the skillet to speed the process along, but watch that it doesn’t burn on the bottom. When cheeses are completely melted and mixed it is ready to serve.
1 pound frozen spinach, 8 ounces cream cheese, 1/4 cup Parmesan cheese, 1/4 cup cheddar cheese, 1/2 cup mozzarella cheese, 1 cup chopped artichokes
