Marinara sauce

I'm always on the lookout for the perfect marinara sauce. This one looked good and easy as it's a crockpot meal - it was quite tasty and I'd make it again. I served it over gnocchi, and I'm sure it would be just as good on regular spaghetti noodles.

Miller's Marinara

Ingredients:

1/4 cup canola oil (I used olive oil)

1 medium onion, chopped

1 (28 ounce) can crushed tomatoes

1 (8 ounce) can tomato sauce

1 (10.75 ounce) can tomato puree

2 1/2 tablespoons garlic powder

2 tablespoons dried oregano

2 tablespoons dried basil

2 tablespoons salt

2 tablespoons white sugar (omitted)

2 teaspoons ground black pepper

Directions:
Heat the oil in a skillet over medium heat, and saute the onion until tender.
In a slow cooker, mix the onion, crushed tomatoes, tomato sauce, tomato puree, garlic powder, oregano, basil, salt, sugar, and pepper.
