Kirkland marinara sauce. 3 - 32 oz jars for around $6.50 which is around the same price as the 24 oz jars that Barilla makes (when it's on sale.) OU hashgacha.
Thinner and not spicy (which I prefer.) I would stick with the Barilla if you can find it for just plain dumping on pasta, but we used it last night with ground beef and onions to make a hurry-up dinner and it was fine. With the number of teenagers I feed on the weekends, the Kirkland is good value for the money.
