Greek red sauce

I'm not sure if this is really a Greek red sauce or not, but I love it! My dad makes it all the time to put over rice when we have shish kabobs and whatnot.

1-2 tbsp. olive oil
1-2 cloves of garlic, minced
1 small onion, chopped

1 15 oz. can tomato sauce

1 14.5 oz. can diced tomatoes

1 tsp. Italian seasoning or oregano

1/4 tsp. allspice

1/8 tsp. cinnamon

Heat oil in a pan over medium heat. Add garlic and onion and saute until onion is soft. Add in tomato sauce, diced tomatoes, Italian seasoning, allspice and cinnamon. Let simmer for about 20 minutes and serve over rice. Fresh parsley can also be added at the end for a burst of freshness.
