In the bowl of your slow cooker, combine the stock, carrots, onion, pesto, rosemary, red pepper flakes, 1 teaspoon salt, and 1/4 teaspoon pepper. Add the Parmesan rind, if using. Cover and cook on low for 6-7 hours.
6 cups low-sodium chicken or vegetable stock, 3 carrots, 1/2 medium yellow onion, 1/4 cup basil pesto, 2 sprigs fresh rosemary, 1/2 teaspoon red pepper flakes, kosher salt and black pepper, 1 Parmesan rind
About 30 minutes prior to serving, remove the Parmesan rind and the rosemary sprigs, and stir in the cannellini beans. Put the lid back on and leave the slow cooker on low.
2 (15 ounce) cans cannellini beans
After the beans have been in for 20 minutes, stir in the couscous, kale, and lemon juice. Cover and continue to cook on low just until the kale wilts and the couscous is tender. (This takes 10-12 minutes for me, but will vary a bit depending on exactly how hot your slow cooker gets.)
3/4 cup pearl couscous, 2 cups kale, 1 Tablespoon fresh lemon juice
Sample the broth and season with more salt and pepper to taste.
Ladle into bowls, sprinkle generously with Parmesan, and enjoy!
