Before starting, preheat the oven to 450°F. Wash and dry all produce. Drain and rinse chickpeas, then pat dry with paper towels. Add chickpeas, half the Shawarma Spice Blend and 2 tbsp (4 tbsp) oil to a parchment-lined baking sheet. Season with salt and pepper, then toss to coat. Peel garlic, then toss peeled cloves with 1/2 tbsp (1 tbsp) oil on a small sheet of foil. Wrap tightly and place on the same baking sheet.

Roast in the middle of the oven until chickpeas are almost crispy, 10-12 min. When almost crispy, carefully remove the baking sheet from the oven, stir chickpeas, then cover loosely with foil (or another baking sheet). Return the baking sheet to the oven and continue to bake until chickpeas are crispy, 6-8 min.

Meanwhile, cut flatbreads into 1-inch pieces. Add flatbreads, remaining Shawarma Spice Blend and 1 tbsp (2 tbsp) oil to another parchment-lined baking sheet. Season with salt and pepper, then toss to coat. Bake in the top of the oven until golden-brown and crispy, 5-6 min.

Meanwhile, halve tomatoes. Thinly slice green onions. Core, then cut pepper into 1/2-inch pieces. Drain, then roughly chop olives. Roughly chop parsley.

Add roasted garlic cloves to a large bowl. Using a fork, mash cloves. Add vinegar, 1 tsp (2 tsp) sugar, 2 tbsp (4 tbsp) oil and 1 tbsp (2 tbsp) water. Season with salt and pepper, then whisk to combine.

Add roasted chickpeas, green onions, tomatoes, peppers, parsley, olives and half the feta to the bowl with dressing. Toss to coat. Divide spiced flatbreads between bowls, then top with chickpea mixture. Sprinkle remaining feta over top.
