In a large bowl add ground turkey, garlic powder, onion powder, and Italian seasoning; mix well by hand.
Shape the turkey into small meatballs approximately 3/4 inch in diameter. Place meatballs into crockpot.
Pour the spaghetti sauce over meatballs and sprinkle with cheese. Cook on low for 4 hours or until no longer pink inside.
About 30 minutes before meatballs are done, prepare spaghetti as directed on package.
While spaghetti cooks, prepare salad: Toss together lettuce, dressing, and cherry tomatoes in a large bowl.
Serve meatballs and sauce over pasta, with salad and raspberries on the side.
