This is definitely comfort food. We used black olives, but green olives probably would add more flavor. It did need some salt to bring out the flavor.
WOW, Diane. A Yummilicious side!! I didn't use the Cheddar topping only sprinkled with some freshly grated Parma. WONDERFUL! Love the olives and--since you didn't specify which kind--I used green stuffed. Will made this again!
