More pasta sauce!

I think it's clear that there is some strong Italian blood in these Mexican Irish veins if my propensity for tomato sauces is any indication. My grandmother (the Irish part) made the yummiest bolognese around though, so maybe we're just creative geniuses with tomatoes.
Rather than purchase a jar of sauce last night, I figured I'd use up some of my many cans of tomatoes and make my own to go with the whole wheat three cheese tortellini I had.
2 cloves of garlic - smashed
1 medium onion - cut in half and very thinly sliced
2 cans tomatoes - I used one can of plum tomatoes with oregano and basil, and one can of diced tomatoes
3/4 can tomato paste
1-2 tbsp dried basil (to taste)
pinch of oregano
pinch of red pepper flakes
glug of olive oil

I went twice around my pot with the oil, let it heat over medium high, then added the garlic and onion and cooked until fragrant and just soft. Then I added the two cans of tomatoes and let cook for a few minutes.
Next, I added the tomato paste and the herbs, mixed everything well, turned it down to low and put a lid on it to simmer.
Stirring occasionally, once it looked thick enough I was done. I didn't even need to add salt and pepper it was so perfectly yummy and ready to go. I put half of it in the freezer, and mixed in 1/4 cup or so of fat free half and half into what was still in the pot to make a pink sauce. At that point I felt like I could've gone with another clove of garlic, but darn it was tasty.
