1 cup milk
2 generous heaping T of Parmesan cheese
1/2-1 t. dry basil (1-2 T fresh)
8 oz. spinach or more for more sauce (fresh or frozen broken apart)
1/2 box cooked and drained pasta
Melt butter in a medium sauce pan. Add flour and mix with a spoon till flour is fully blended. Cook for 1 minute or so, add milk all at once and give it a good stir. Don’t worry at this point if it seems slightly lumpy, those will dissolve as this cooks. Add cheeses, pepper, and basil. Cook for 5 minutes stirring until you see the sauce thickening enough to coat the spoon. Taste test and added 1/4-1/2 t. salt if needed. Add spinach. Cook a few minutes more till hot again, place on pasta.
