One Pot Pasta with Spinach and Tomatoes

Since the last One Pot Pasta recipe was such a hit, I thought I would post another one.  I have not tired this yet but it is on the menu for the next week.  I found this on the Cooking Light website, so not only is it suppose to be delicious but good for you too!!! 

1. Heat a dutch oven or large saucepan over medium heat.  Add oil, swirl to coat.
2. Add onion and garlic to pan; sauté 3 minutes or until onion starts to brown. 
3. Add tomatoes,
   stock, oregano,
   and pasta, in
   that order.
   Bring to a boil. 
4. Stir to submerge noodles in liquid.
5. Cover, reduce heat to
   medium-low, and cook 7 minutes
   or until pasta is almost done. 
6. Uncover; stir in salt.
7. Add spinach
   in batches,
   stirring until
   spinach wilts.
   Remove from
   heat; let stand 5 minutes.
8. Sprinkle with cheese.
