Penne with Spinach Sauce

Last week I had one free night of not working and had time to run to the store (our fridge was basically empty) and make this delicious recipe here.  The sauce had just enough flavor without being overbearing and it was pretty healthy as well.  I used whole 100% whole wheat penne with flax instead of enriched pasta and added fresh diced tomatoes to give that extra flavor and freshness.

After cutting up fresh spinach, add the hot pasta directly over it to slightly wilt it.
Use a little leftover pasta water to add to the sauce to thin it out
just a bit (Not too much)

Stir it all together, serve and top with fresh diced tomatoes
and fresh grated pecorino.
