Heat a large skillet over medium heat. Add the beef/turkey, onions, mushrooms and seasonings. Simmer until cooked
Add crushed tomatoes and sauce, bring the pan to a gentle boil. Reduce the heat to low and simmer for 10 minutes. Remove from heat and set aside
In a large bowl, combine the Cottage Cheese and Spinach. Stir to mix well. Set aside.
Spray a 12-cup muffin tin with nonstick cooking spray. Place 1 wonton wrapper into each of the 12 cups, pressing firmly in the bottom of the cup and up the sides
Spoon in Cottage Cheese mixture, using about half for the 12 muffin cups
Spoon in half of the beef/turkey and tomato sauce mixture, again using about half.
Sprinkle with mozzarella
Gently press another wonton wrapper on top of the mozzarella layer
Repeat the process by distributing the remaining Cottage Cheese, then the remaining tomato sauce/meat mixture, and finally the rest of the shredded mozzarella
Bake for about 10 minutes, or until the cheese has melted
Let the cups cool for 5 minutes then remove them from the pan, and serve!
