creamed spinach crockpot

fresh spinach (this filled my entire salad spinner)
1/2 block cream cheese
1 small container greek yogurt, plain
cornstarch (~1 tsp)
1/3 cup mozzarella cheese

wash spinach and spin dry.  Chop in large pieces, add spinach, cream cheese and yogurt to the crockpot, cook on high ~1 hr until spinach wilts.  Add mozzarella cheese and cornstarch and cook ~30 mins on low.  Add more cornstarch to thicken to desired consistency and serve.
