Pre-heat the oven to 375 degrees. Prepare a sheet plan with unbleached parchment paper and 8-9 skewers.
In a small bowl, mix the sea salt and sumac and set aside.
Pat the chicken dry and cut the chicken into about ½ inch cubes. Drizzle with a couple teaspoons of olive oil and toss to coat lightly. Rub the sumac and sea salt mixture over each chicken cube.
Pierce the chicken cube with a skewer and then add a square of onion and then a square of fennel. Do this about 3 times per skewer.
When the skewers are prepared, set them on the prepared sheet pan and cook for 12-13 minutes or until almost fully cooked through.
Meanwhile, mix the pomegranate molasses, maple syrup and black pepper in a sauce pan and heat over medium heat until slightly thickened – enough to coat the back of a spoon.
When ready to serve, drizzle the pomegranate glaze on the skewers
Optional: Garnish the skewers with fresh pomegranate seeds
