Transfer the bell pepper mixture to a 5- or 6-quart slow cooker; stir in the beef stock and ketchup. Place the steak, oil, black pepper, and 1 teaspoon of the salt in a medium bowl, and toss to coat. Submerge the steak in the bell pepper mixture in the slow cooker. Cover and cook on LOW until the meat is very tender, about 8 hours.
Transfer the steak to a large bowl, reserving the sauce in the slow cooker. Shred the steak pieces with 2 forks. Toss the shredded steak with 1 cup of the reserved sauce in the bowl, and stir in the chopped green olives.
Stir together the beans and 1⁄4 teaspoon of the salt in a medium saucepan, and cook over medium until heated through, about 5 minutes. Keep warm. Prepare the rice according to the package directions, and season with the remaining 1⁄2 teaspoon salt. Serve the shredded steak mixture with the rice, beans, and remaining reserved sauce from the slow cooker.
