Once our son was diagnosed with celiac disease, we thought our pizza days were surely over.
We found Schar Pizza Crusts and Ragu Homemade Style Pizza Sauce!
Per a phone conversation with Ragu, they assured that all their pizza sauces are gluten free. The traditional pizza sauce lists modified food starch on their label. The lady at Ragu said that it is from corn. I personally use the Homemade Style.
A note for diabetics: 1 serving = 1/3 of a pizza crust = 30g. The plate shown above contains 1 serving.
