In a small bowl whisk together raspberry vinegar, olive oil, sugar, pepper, and garlic. Reserve 1 tablespoon of the oil mixture; set aside.
Rinse fish; pat dry. Place fish on the greased, unheated rack of a broiler pan; tuck under any thin edges. Brush fish with reserved oil mixture. Broil 4 inches from the heat for 4 to 6 minutes per 1/2-inch thickness or until fish flakes easily with a fork.
Meanwhile, cook pasta in boiling salted water according to package directions; drain. Return pasta to saucepan. Pour remaining oil mixture over pasta; toss to coat.
Flake cooked salmon. Add salmon and strawberries to pasta; toss gently. Transfer to a warm serving platter. Sprinkle with green onions.
