Oven Roasted Tomato Sauce

2 lbs tomatoes, quartered
1 medium onion, roughly chopped
8 cloves garlic
3 Tbsp olive oil
2 Tbsp fresh oregano or basil
1 tsp kosher salt

Preheat oven to 375 degrees and toss all ingredients in 9 x 13 glass baking dish.  Roast for 1 hour.  Remove pan from oven, cool slightly and transfer all ingredients to blender, and blend until smooth.  Serve or store in refrigerator or freezer, or can.  I've done all three, I love this sauce, I use it as spaghetti sauce, pizza sauce, dipping sauce for quesadillas, everything!
