Trim fat from chops. Sprinkle chops lightly with salt and pepper. For a charcoal grill, grill chops on the rack of an uncovered grill directly over medium coals until desired doneness, turning once halfway through grilling. Allow 12 to 14 minutes for medium-rare (145 degrees F) and 15 to 17 minutes for medium doneness (160 degrees F). (For a gas grill, preheat grill. Reduce heat to medium. Place chops on grill rack over heat. Cover and grill as above.)
Meanwhile, in a medium saucepan combine beans, celery, green onion, and 2 tablespoons of the Chile Butter. Cook over medium heat until heated through. Stir in lime juice. Top each lamb chop with a slice of Chile Butter and serve with bean mixture. If desired, garnish with lime wedges. Makes 4 servings, 2 chops each.
In a small bowl stir together butter, cilantro, jalapeno peppers, garlic, chili powder. Place on waxed paper; form into a log. Wrap well; chill for 1 hour or overnight. Store in refrigerator for up to 2 weeks or freeze for up to 1 month.
