Soak 8 wooden skewers in water for at least 15 minutes. Combine the pork, tomatoes, garlic, lemon, 2 tablespoons of the oil, ¾ teaspoon salt, and ¼ teaspoon pepper in a medium bowl.
Heat broiler. Thread the pork, tomatoes, garlic, and lemon on the skewers and broil, turning occasionally, until the pork is cooked through and the lemon wedges are lightly charred, 5 to 7 minutes.
Meanwhile, heat the remaining 2 tablespoons of oil in a small pot over medium heat. Add the lima beans, rosemary, and ¼ teaspoon each salt and pepper and cook, tossing occasionally, until the beans are warm, 2 to 3 minutes. Serve with the kebabs.
