Marinate the chicken: In a mixing bowl, whisk together Marie's Original Coleslaw dressing, paprika, cumin, cinnamon, garlic, red pepper flakes, lemon zest, lemon juice, salt, and pepper.

Alternate pieces of chicken and onion onto each skewer, then place skewers in a shallow baking dish. Pour the marinade mixture over the chicken skewers, coating them well. Cover and refrigerate for at least 1 hour or up to overnight.

Prepare the slaw: In a large bowl, stir together the cabbage, onion, parsley, and Marie's Original Coleslaw dressing until thoroughly combined. Sprinkle with red pepper flakes for an extra kick of spice, if you like.

Preheat grill to medium-high heat. Brush the grates with a little oil to coat and grill the marinated chicken skewers. Turn skewers occasionally until chicken is fully cooked, about 15 minutes. Transfer to a platter and serve immediately with warm pita bread, slaw, sliced tomatoes, and extra Marie's Original Coleslaw dressing for drizzling.
