Place Aleppo Pepper and warm water in a small dish and let rest for 5 minutes, until pepper thickens and becomes more like a paste.
Cut chicken into chunks of about equal size and set aside.
Add all remaining marinade ingredients to a medium sized dish and stir to incorporate.
Reserve ½ cup marinade and refrigerate until ready to serve skewers.
Place remaining marinade and chicken in a Zip Lock bag.
Marinate maximum 1 hour. Chicken and marinade can rest at room temperature. Prepare Rosemary and Garlic Roasted Potatoes and start cooking, if using.
30 minutes before grilling, place wooden skewers in water.
Chop any fresh vegetables to serve with the skewers: tomatoes, cucumbers, peppers and garnish with Kalamata olives and some plain yogurt, along with remaining marinade.
Thread skewers, discarding marinade. Grill chicken skewers and serve immediately with warm flatbreads and/or potatoes and sides.
