This recipe had a lot wrong with it. I followed it carefully. Tomato paste was called for in the directions but not the ingredients. I added @ 2T, and I used the 6-qt slow cooker on high for 3 hours. That was definitely the wrong size cooker. 2-qt would have been appropriate. As it was, cooked on high, the liquid was reduced to a sludge. I added the cheese, which was overpowered by the tomato taste. Even my husband, who finds good in almost everything I make agreed that it was inedible. We had to throw it out.
