Best Pizza Sauce. Ever.

This sauce has a kick! But is delicious. From my future mother in law...

Pizza sauce (enough for 2 pizzas)
8 oz tomato sauce
6 oz tomato paste
1 tsp oregano
1 tsp salt
1 tsp pepper
1 tsp crushed garlic
2 T sugar
1 tsp lemon or lime juice
1 T white vinegar
1 tsp red pepper flakes (or to taste)

Mix all and simmer for 5 minutes
