To deglaze any browned bits of onion from the pot, add vegetable broth and scrape with spatula. (This adds flavor to the broth and helps prevent the IP's auto-shutoff "burn" feature.)
Add canned diced tomatoes (with juices) canned tomato sauce, and vegetable broth. Next stir in sugar, basil, and oregano.
Set to HIGH pressure for 15 minutes and allow to come to pressure, allowing a natural pressure release for about 10 minutes.
