Preheat oven to 350°F.
In a medium saucepan, brown ground turkey.
Bring a large pot of water to a boil. Add cabbage leaves and simmer until tender, about 5 minutes. Remove from pot and set aside to dry on a paper towel.
Add turkey to a large mixing bowl and stir in carrots, onion and water chestnuts.
In a separate bowl, combine sauce ingredients and add to turkey mixture.
Line a 9x13” baking pan with cabbage leaves. Place 1/3 up of filling in the center of the leaves. Fold in the sides and roll. Brush tops with olive oil then place wraps seam-side down and bake for 35 – 40 or until lightly browned on top.
