MAKE THE CHICKEN
In a bowl, combine olive oil, lemon juice, garlic, and all the spices to make the marinade.
Add the chicken thighs and coat well. If you have the time, cover and marinate for at least 30 minutes or up to overnight.
Heat a skillet or grill pan over medium-high heat and cook the chicken for 5 to 6 minutes per side until golden brown and cooked through.
Let rest for a few minutes, then chop into bite-sized chunks.
MAKE THE POTATOES
Peel the potatoes and cut them into small, even chunks.
Toss the potatoes with oil, cornstarch, salt, and black pepper until well coated.
For the air fryer, cook at 400°F for 20 to 25 minutes, shaking halfway through, until crispy and golden.
For the oven, roast at 425°F for 35 to 40 minutes on a parchment-lined baking sheet, flipping halfway through, until crispy and golden.
MAKE THE GARLIC SAUCE
In a bowl, whisk together mayonnaise, sour cream or yogurt, garlic, sugar, lemon juice, black pepper, and water.
Mix until smooth and creamy, then adjust seasoning to taste.
ASSEMBLY
Add a base of crispy roasted potatoes to each bowl.
Layer shredded lettuce over the potatoes.
Add the chopped shawarma chicken on top.
Sprinkle on chopped pickles.
Finish with a drizzle of garlic sauce and pomegranate molasses.
