Cook macaroni according to package directions. In a colander, drain macaroni and rinse with cool water. Set aside.
While macaroni cooks, rinse and dice bell pepper. Peel and finely chop onion. Peel and mince garlic.
Grate cheese.
In a large skillet over medium heat, add turkey, bell pepper, onion, and garlic. Cook, crumbling the meat with a mixing spoon or rubber spatula, until meat is no longer pink, about 15 minutes. In a colander, drain off fat.
Return meat mixture to skillet. Stir in macaroni, tomatoes with their juices, thyme, salt, and pepper. Sprinkle with cheese. Cover and cook over medium heat until cheese is melted, 5-7 minutes.
