Tomato and Spinach Rotini

I tried this recipe today, turned out good.

My changes:
1. No meat.
2. Sauteed a few onions and mushrooms, then added the spinach and tomatoes to it.
3. Added half a can of pasta sauce because 1 can of tomatoes leaves the pasta still too dry. Either add pasta sauce or double the amount of canned tomatoes.

• 2 cups rotini
• 1 package spinach (7 cups)
  
• 1 can Italian style diced tomatoes, undrained
• 1 cup mozzarella cheese, shredded
• 2 Tbsp grated parmesan cheese
• 1/2 onion
• 1 small can mushrooms
• 1/2 can pasta sauce

Cook pasta. Cook spinach with tomatoes, onion, mushrooms. Add cheeses. Mix sauce with drained pasta.
