Spinach Marinara Sauce

First I have to say - yay for crockpots!
Second I really loved this sauce. It is wonderful but Drew? He said:

"This is the best sauce I have ever put in my mouth."

And then he wanted to know could he just eat it as soup... I think he liked it!

• 1/4 cup olive oil
• 1 onion, finely diced
• 1 finely grated carrot
•  2 cups chopped fresh spinach
• 5-6 cloves garlic, minced
• 12 oz tomato paste
• 28 oz peeled tomatoes, pureed, with juice
• OR 28 oz can crushed tomatoes, with juice
• 15 oz can diced tomatoes, with juice
• 4 teaspoons oregano
• 4 teaspoons basil
• 1-2 tsp ground red pepper
• 4 teaspoons salt

Heat oil in a skillet, saute onions and carrots until soft, add  garlic, oregano, basil, salt, pepper, salt. Continue to saute until garlic and herbs are fragrant.

Add to the crockpot: spinach and all tomato products and the sauteed mixture.

Cook on high for 4 hours or so. Or cook on low for longer - 6-8 hours. (From this point I really don't think you could mess it up. It just needs to cook a good long time so the flavors mix.)

PS - Crushed tomatoes are fine. I did the pureed ones to use up some whole plum tomatoes I had in the pantry.
