Preheat grill to medium-high heat.
Place beef into a resealable plastic bag with Caesar salad dressing; seal and refrigerate for 30 minutes.
Prepare fettuccine according to package instructions. Drain and toss with butter, salt and pepper to taste; hold warm.
While pasta cooks, remove beef from bag and discard marinade. Alternate with vegetables on skewers. Place kabobs on grill and cook until beef reaches desired doneness, about 4 minutes per side for medium.
Divide cooked pasta equally among 4 plates and top with one kabob per person. Serve immediately.
