Packed with veggies and flavored with a little bacon, this recipe will warm you up on a chilly day. This hearty soup is as versatile as it is delicious. Substitute collards for the kale, use another type of small dried beans, or add heat with red pepper flakes. And because it’s made in a slow cooker, you don’t have to stand over the stove stirring it for hours. Just prepare the bacon in the microwave, crumble it, then add it along with the vegetables and other ingredients to the slow cooker. Cover and cook on LOW until the potatoes and beans are fork-tender, 5 1⁄2 to 6 hours.
