Thread meat and peppers onto skewers and brush with 2 tablespoon oil. Season with salt.
Cook pasta in very salty water until done. Drain and set aside.
Meanwhile, heat grill to medium-high; oil grill grates and cook kabobs, turning frequently, until the meat is done, 7 to 9 min for medium. Remove from grill. Using a clean brush or spoon, coat kabobs generously with pesto.
Toss drained pasta with Parmesan, 1 tablespoon oil and black pepper; serve with kabobs.
Notes
Brushing on pesto adds major flavor to these tender sirloin skewers.
