Recipe: Parmesan Spinach Chicken

I made this recipe up tonight, and it was wonderful.  The Girl even liked it!  And she doesn't normally like spinach.  I'd say that's a win.  It was ridiculously easy, too.

Parmesan Spinach Chicken

6 chicken tenders, or 3 boneless skinless chicken breasts, cut into strips.
1 10-oz box frozen chopped spinach, thawed and drained
1/3 c grated Parmesan cheese
2 tsp Italian seasoning
1 Tbsp butter
1/4 c onion, chopped fine
1 Tbsp flour
1/2 c skim milk
1/4 c mozzarella cheese

Preheat oven to 350 F.  Combine Parmesan cheese with seasoning and roll the chicken in it to coat.  Place the chicken in a baking dish.  In a small saucepan, melt butter and cook onion until soft.  Stir in the flour and whisk until thickened slightly.  Add milk and simmer for a few minutes until bubbly.  Stir the spinach into the sauce.  Spoon on top of the chicken and bake for about 30 minutes.  Sprinkle with the mozzarella and bake for an additional 5 minutes until melted.  Enjoy.
