Preheat a gas or charcoal grill.

In a bowl, add zucchini, mushrooms, onion, red pepper, olive oil, and za’atar. Stir to combine. Transfer the veggies to a grill basket and cook, stirring often, until the veggies are tender, about 7-10 minutes. Season with salt and pepper to taste at the end.

If you’re serving immediately, brush both sides of the pita with olive oil. Grill for 30-60 seconds on each side, or until the pita is toasted and warmed through.

To assemble, add 2-3 tablespoons of hummus to each piece of pita. Top with about 1/4 cup of the grilled veggies. Sprinkle with crumbled Feta cheese and garnish with chopped parsley.
