Why did my tahini sauce turn thick and clumpy?
Tahini can seize when it meets acid. It is normal. Keep whisking and add water a tablespoon at a time. It will relax into a smooth, glossy sauce.
Can I make this vegetarian?
Yes. Swap the chicken for chickpeas or crispy tofu.
Chickpeas: Pat dry, sauté with the same spices until lightly browned, then build the pita the same way.
Tofu: Press extra-firm tofu for 10 to 15 minutes, cut into small cubes, then toss with the spice mix plus 1 tablespoon olive oil. Cook in a hot skillet until deeply browned and crisp, 8 to 10 minutes, turning often. (A little cornstarch, 1 to 2 teaspoons, makes it extra crisp if you are into that.)
What kind of pita works best?
Look for pocket pitas that feel soft and flexible. 6 to 7-inch pitas are perfect for stuffing. If your pitas crack, warm them longer or wrap in a damp paper towel and microwave for 15 to 20 seconds.
How do I keep the pita from tearing?
Warm it, then cut just the top edge and gently open the pocket with your fingers. Also, do not overstuff on the first pass. Add a little sauce, then fillings, then more sauce.
Can I grill the chicken instead?
Absolutely. Grill over medium-high heat until cooked through, then slice thin. The sauce loves that smoky char.
