Pasta w/ Spinach, bacon, & Parmesan cheese

This is super easy, fast, and healthy.

1 lb your favorite pasta (keep a couple ladles full of the pasta water)
couple handfuls fresh spinach
4-5 strips turkey bacon (or regular if that's what you use)
1 cup Parmesan cheese
You can add cooked chicken also if you like
1/2 stick butter
salt/pepper

cook pasta according to directions, drain (saving some pasta water)
add butter,pasta water, spinach, bacon bits, and Parmesan. Toss, add salt and pepper to taste.

I forgot to take a picture of this and we don't have leftovers so you will have to use your imagination.
