3 cups fresh spinach, chopped
12 slices good pepperoni

1 cup sliced fresh mushrooms
1 cup sliced onion
3 cups shredded Mozzarella cheese

Brown the ground meat first in a separate skillet, add the pizza sauce and stir to combine.

Put 1/2 of the meat-sauce into the slow cooker, followed by 1/2 the fresh spinach, 1/2 the pepperoni, 1/2 of the olives, 1/2 of the mushrooms, 1/2 the onion, and 1/2 the Mozzarella cheese.

Repeat the layers using up the remaining ingredients, ending with the Mozzarella cheese covering the top.

Turn off the heat and let it sit for 15 minutes before cutting.

Will serve 6 to 8.
