In a medium bowl add Icelandic Provisions Skyr and lemon juice. Mix well. Add garam masala, paprika, ginger, red pepper flakes, coriander, cumin, turmeric, fenugreek, and garlic, and whisk until well combined. Set aside.
Place chicken in a small bowl and coat with the skyr sauce, making sure to save some extra sauce for later.
Cover and place the chicken in the refrigerator and marinate for 5 to 60 minutes, depending on your taste preference. Note: the longer the chicken marinates, the stronger the flavors will become.
When the chicken is ready, preheat the grill, and grease the grates with ghee to prevent the chicken from sticking. Place chicken thighs on grill and cook for about 4-5 minutes. The chicken should be nicely browned and slightly charred on one side.
Flip chicken, and spoon remaining marinade on top. Grill for another 4-5 minutes, or until chicken has reached an internal temperature of 165° Fahrenheit.
Place the chicken on a serving platter, garnish with lemon slices, and serve.
