Prepare the ingredients as instructed above.
Cook the rice: Prepare basmati rice according to the package directions. Once cooked, fluff with a fork and keep warm, covered.
Make the shawarma marinade: In a bowl, mix garlic, coriander, cumin, cardamom, smoked paprika, salt, black pepper, lemon juice, and olive oil. Add chicken and toss to coat. Set aside to marinate.
Prepare the garlic sauce: Blend garlic, oil, salt, pepper, and lemon juice until smooth and fluffy. Set aside. (Optional: for less pungent garlic, boil it in water for 5 minutes. Then drain)
Grill the chicken: Heat a grill over medium heat. Grill the marinated chicken on both sides until grill-marked and the internal temperature reaches 160°F (71°C). Let rest for 5 minutes, then slice.
Assemble the bowls: Portion the rice. Top with lettuce, cucumber, tomato, red onion, and pickles. Add grilled chicken slices and drizzle with garlic sauce.
Make the watermelon mint drink: In a blender, combine all ingredients until smooth. Strain (optional): Pour the mixture through a fine mesh strainer into a pitcher or jar, pressing with a spoon to remove pulp (optional).
Serve the shawarma bowls with garlic sauce, fresh watermelon, watermelon mint drink, and baklava for dessert.
