On a rimmed plate or in a pie dish, soak the bread in the milk to soften.
In a large bowl, crumble the ground turkey and season with salt and pepper. Squeeze the milk from the bread over the meat, then add the bread. Add 1/4 cup chutney, 1/4 cup yogurt, the egg, chile, scallions, ginger, garlic, nuts, curry powder, cumin and cilantro. Mix and form into 4 patties.
Heat a griddle or large skillet over medium-high heat. Brush with melted butter (or oil). Add the patties and fry, turning once, until opaque, about 12 minutes.
Fold the flatbreads. Fill each with a patty and the toppings of your choice. Dollop with yogurt and chutney.
