Cook macaroni in boiling water 10 minutes. Add broccoli and carrots and cook until macaroni is tender, 2 minutes longer. Drain and rinse with cold water to cool.
Place macaroni mixture in a bowl or casserole dish. Toss with half of salad dressing and sprinkle with 1/4 teaspoon pepper. Layer turkey, zucchini and tomatoes on top of macaroni mixture.
Drizzle with remaining salad dressing and sprinkle with remaining 1/4 teaspoon pepper. Cover and refrigerate at least 2 hours or overnight.
