Wash off the eggplant and cut it into bite-sized pieces.
Blot the eggplant pieces with a paper towel to remove any excess water. Then place the eggplant pieces on a silpat-lined baking tray.
Sprinkle the arrowroot powder onto the eggplant and toss the eggplant pieces in the arrowroot powder.
In a small bowl, mix the olive oil with the za'atar and pour it over the arrowroot-dusted eggplant pieces. Toss well until eggplant pieces are well coated.
Place the eggplant in the oven and let the pieces bake at 400 degrees for 10-12 minutes. Remove from the oven and, using a large spoon, toss the eggplant pieces over as best you can.
Place back in the oven and bake for another 10 minutes.
Serve garnished with fresh parsley and chili flakes.
