This is an easy pizza sauce I make all the time. As long as you have canned tomatoes, you can make this sauce easily within 10 minutes.
Storebought pizza sauce is expensive and doesn't last...I always have canned tomatoes on hand, so I made this easily using things I had in the house.
The only key is to crush the tomatoes well, I guess. The sauce has a more complex flavor if you add herbs, but it's fine without them too. It's so easy to make, you'll be surprised.
Enjoy Japanese food around the world.
