How to Make It
In a large saucepan, cover the wheat berries with 3 inches of cold water and bring to a boil. Simmer over moderate heat until tender, about 1 hour. Drain and rinse under cold water. Drain again and let cool.
Meanwhile, line a small strainer with a coffee filter or a moistened paper towel. Spoon the yogurt into the filter and let drain for 15 minutes. Discard the liquid. Transfer the yogurt to a large bowl and whisk in the vinegar, mustard, garlic and chile. Whisk in the olive oil and season with salt and pepper. Add the turkey, tomatoes, olives, basil, mint and wheat berries and toss. Season the salad with salt and pepper, transfer to a bowl and serve.
Hard red wheat berries are whole, unprocessed, reddish brown kernels of wheat that have been husked. Wheat referred to as hard is high-protein and grown in colder climates. Look for the berries at health-food stores and in the organic section of the supermarket.
