How to Make It
Preheat oven to 350° and coat 13 x 9-inch pan with nonstick spray.

Microwave the sausage patties for 40 seconds and then crumble them.
Evenly top the hash browns with the sliced spinach. Follow with the sausage and 2 1/2 cups cheddar cheese.

Top evenly with the sliced tomatoes and sprinkle with remaining cheese and parsley flakes.
