Homemade Spaghetti Sauce

My mom always brings me her old issues of Woman's World magazine when she comes to visit. I like the magazine for the recipes mostly. Every now and then there's a really great one.

Here's one they had for spaghetti sauce. I'm posting it here with the tweeks I made. It's positively addicting!

Homemade Spaghetti Sauce

1 can diced tomatoes (any kind even with onions or seasoning)
1 medium onion
3-4 stalks of celery (leaves included)
1-2 large carrots (depending on the size)
1/4 cup EV olive or canola oil
1-2 cups fresh spinach
1-2 tbsp fresh garlic
salt/pepper to taste

Chop onion, celery (with leaves) and carrots into medium sized pieces.
Heat oil in a pan and saute onion, celery and carrots for 15 minutes, or until onions are transparent.
Add tomatoes, salt and pepper.
Simmer on low for 25 - 30 minutes, stirring occasionally.
5 minutes before done, add spinach and garlic, stir.
Toss with 1 lb brown rice pasta or other pasta.

Approximately 6 servings.
