Creamy Tomato Pasta Sauce...

3 Tbsp Olive Oil
1 Onion (diced)
3 Cloves of Garlic
28 oz can of pureed Tomatoes
1 Tbsp Dried Basil
1 tsp Dried Oregano
1 1/2 tsp Sugar
1/2 tsp Salt
1/4 tsp Pepper
1 C Heavy Cream

In a saucepan, saute onion and garlic in olive oil over medium heat.  Do not burn!  Add tomatoes, basil, sugar, oregano, salt & pepper.  Bring to a boil and continue to boil as liquid reduces.  About 5 minutes.  Remove from heat; stir in cream and butter.  Reduce heat and simmer 5 more minutes. 

(I added two cups of mini shrimp and tossed the sauce with a box of (cooked) mostaccioli.  We all liked it.  That's a plus and a surprise...)
