Rinse turkey breast fillets with cold water, pat dry and dice. Peel the garlic, chop it finely and mix it with the soy sauce, sugar and spices. Marinate the turkey breast cubes for 45 minutes.
Then take it out and let it drain. Put the cubes on skewers and grill under the grill for 10 to 15 minutes or fry in a pan with a little oil. Turn more often and brush with the marinade again and again.
