To make filling: Combine onion, mushrooms, carrots, soy, vegetable oil, garlic, pepper and sugar. Let stand for two hours in a tightly covered bowl. Place the turkey in a deep, oven-proof roasting pan and cook slowly, partially covered in a 300° F oven until the meat easily pulls away from the bone, about two hours.* Remove the turkey from the pan and shred the turkey on a plate.
To assemble wraps: Warm the tortillas and lay each on a work surface. Place a piece of lettuce on each tortilla. Distribute the pulled turkey and onion-mushroom mix evenly. Add basil leaves and part of the rice mix to each wrap. Finish with a slice of Gouda. Wrap the tortilla by folding the sides in and over the mix and gently folding the back flap up. Roll tightly.
Servings: 6 wrap sandwiches
