Homemade pesto comes together quickly before being spread on a baguette and topped with grilled steak and cheese.
Prepare Smoky Cilantro Pesto. Place cilantro, pine nuts, chipotle peppers, garlic, lime juice and black pepper in food processor container. Cover; process until finely chopped. Add cheese; pulse on and off until just combined. With motor running, slowly add oil through opening in cover, processing until smooth.
Spread 1/4 cup pesto evenly onto beef steaks. Place steaks in glass dish. Cover and marinate in refrigerator 15 minutes to 2 hours. Cover and refrigerate remaining pesto.
Place steaks on grid over medium, ash-covered coals. Arrange 12 bread slices around steaks. Grill steaks, covered, 11 to 14 minutes (over medium heat on preheated gas grill 12 to 16 minutes) for medium rare (145°F) to medium (160°F) doneness, turning occasionally. Grill bread slices 2 to 3 minutes or until lightly toasted, turning once. Remove bread slices from grill. Repeat with remaining 12 bread slices.
Spread 2 teaspoons remaining pesto on each toasted bread slice. Carve steaks into thin slices. Place beef slices evenly over bread slices. Top evenly with 1/4 cup cheese and chopped cilantro. Serve immediately.
