What is good pizza sauce for flat bread pizzas for a food tent
I am looking to add flat bread pizzas to the bratwurst and hot dogs I currently sell in my food tent. Wht is a good pizza sauce I can get at at some place like Restaurant Depot, Chef Store, or Costco/Sam's Club? Rao's is supposed to be really good, but I can only find it in small retail jars, and it is many times more expensive than a #10 can elsewhere. I am the only food vendor at events with a captive audience, but I still want to provide a product that tastes good.
I only sell less than ten times per year so I am not set up with a big wholesaler like Sysco or US Foods.
