Spinach Casserole Serves: 9 Mozzarella, feta and processed cheeses are combined with spinach, butter and seasonings, and baked between buttery layers of phyllo dough. I use this as a main dish casserole, side dish or as an appetizer--whatever the occasion calls for. If you prefer, you may also add 1 can of rotel tomatoes to the cheese-spinach mixture for a little zing. Prep Time:15 mins. Cook Time:20 mins. Ready In:35 mins.
