Bring a large pot of water to a boil and salt generously. Cook the orzo according to the package instructions until al dente. Drain, rinse with cold water and drain again. Transfer to a large bowl.
In a small bowl, whisk together the ranch dressing and lemon zest and juice. Toss the mixture with the orzo and season with salt and pepper. In layers or strips, add the feta, olives, tomatoes, cucumber and red onion. Garnish with the Crispy Chickpeas and fresh mint.
Add the oil to a large skillet and heat over medium heat until shimmering. Add the chickpeas and fry, stirring occasionally, until browned and crisp, about 10 minutes. Using a slotted spoon, transfer the chickpeas to a bowl, season with the za'atar and toss to coat. Let drain on a paper towel-lined plate.
