Spinach Pizza

I made up this recipe with the help of another recipe, so some things may have to be tweaked a little bit to your liking, but I think it tastes great. (This is not a low-fat pizza, but it does have spinach, so that's good.)

1/4 c. butter or margarine
1/4 c. flour
2 c. milk
salt and pepper to taste
1/4 c. Parmesan cheese
1/4 pkg. cooked spinach
1 pkg. mozzarella cheese (however much you like on top)

Melt butter in saucepan, add flour. Slowly mix in milk (will be thin). On medium/low heat, stir constantly until it thickens. Add salt, pepper, and Parmesan cheese and melt. You can either add the spinach in the sauce mixture or put it on top of the sauce on the pizza, whichever you prefer. I use mom's pizza dough recipe. So I roll out the dough, put the sauce on, spinach, and then mozzarella cheese. Cook 425 degrees for 15 min.
