Place the farro in a rice cooker with the broth. Start the rice cooker, or if you don't have a rice cooker, just cook it in a small pan on the stove according to package directions. (Farro takes a minimum of 30 minutes to cook so I always use the brown rice setting on the rice cooker. Soaking it overnight does speed up the cook time, but I never think ahead to do that and it always turns out just fine as long as you cook it long enough to be soft and chewy.) Add the white beans, grap tomatoes, kale, Asiago, and tomato sauce directly into the rice cooker or the pot on the stove. Stir it all up, season with additional salt and pepper and maybe a snip of fresh herbs, and you're done.
