How to Make It
In a 4- to 6-quart slow cooker, combine the short ribs, onion, garlic, tomato paste, chipotles, cumin, ¼ cup water, 1 teaspoon salt, and ¼ teaspoon pepper. Cover and cook until the short ribs are tender, on low for 7 to 8 hours or on high for 5 to 6 hours (this will shorten total recipe time).
In a large bowl, toss the cabbage and radishes with the lime juice, oil, sugar, and ¼ teaspoon each salt and pepper. Refrigerate for up to 12 hours.
Twenty minutes before serving, cook the rice according to the package directions. Serve the short ribs with the rice and cabbage slaw.
