Place chicken in a medium bowl, top with yogurt, and stir to coat completely. Cover and refrigerate for at least 1 hour.
Skewer the chicken onto skewers, packing the pieces together tightly.
Spray a grill or a grill pan lightly with nonstick spray, and bring it to medium-high heat.
Grill for 10 to 12 minutes, covered, carefully flipping about halfway through cook time.
Once cool enough to handle, pull the chicken off the sticks and eat!
