This is a delicious recipe. I receive a farm box from our local Tally Farms and fennel is a usual spring inclusion in the box. The recipe is easy with common ingredients. I did use my oven because I don't have a slow cooker. Just started the recipe at 225 for a few hours and then lowered it to 190 (where I cook my bone broths for hours) to fit my meal plan schedule. I happened to have a few small Dutch potatoes already steamed and include them with the beans. Used the Asiago that I prefer as the cheese shavings.
