Dice the chicken breasts into chunks.
2 large boneless skinless chicken breasts
In a large bowl, mix together the yogurt and seasonings until everything is blended.
1½ cup plain yogurt, 1 inch fresh ginger, 4 garlic cloves, 1 teaspoon garam masala, 1 teaspoon ground cumin, ½ teaspoon red chilli powder, ¼ teaspoon turmeric, 1 tablespoon tomato paste
Place the chicken into the marinade and stir to coat well. Cover with plastic film and place in the fridge for at least 4 hours, or up to 24.
When ready to cook, preheat the oven to 400F / 200c.
Line a baking sheet with foil.
Thread the chicken pieces onto the skewers and place on the lined baking sheet, with a gap in between each skewer.
Once the oven is fully heated, place the chicken in and cook for 15 minutes. Turn the skewers half way through.
After 15 minutes of cooking, turn on the broiler (grill). Cook the skewers under the grill to brown them. Turning a couple of times so that they brown all over.
