Before starting, preheat the oven to 450˚F. Wash and dry all produce. Zest, then juice lemon. Cut potatoes into 1-inch pieces. Add potatoes, lemon zest and 1 tbsp oil to a baking sheet. Season with salt and pepper, then toss to coat. (NOTE: For 4 ppl, use 2 baking sheets, with 1 tbsp oil per sheet.) Roast in the middle of the oven, flipping halfway through, until tender and golden-brown, 20-22 min. (NOTE: For 4 ppl, roast in the top and the middle of the oven, rotating sheets halfway through.)

Halve, peel, then cut onion into 1/4-inch slices. Peel, then mince or grate garlic. Cut tomato into 1/4-inch pieces. Roughly chop parsley. Core, then cut pepper into 1/2-inch slices. Pat chicken dry with paper towels. Season with Shawarma Spice Blend and salt.

Add onions, peppers, 1/2 tbsp oil (dbl for 4 ppl) and half the garlic to a baking sheet. Season with salt and pepper, then toss to coat. Set aside. Heat a large non-stick pan over medium-high heat. When hot, add 1/2 tbsp oil (dbl for 4 ppl), then chicken. Sear until golden-brown, 2-3 min per side. Transfer chicken to the baking sheet with the veggies. Roast in the bottom of the oven until chicken is cooked through, 8-10 min.**

While chicken roasts, add mayo, 1/2 tbsp lemon juice (dbl for 4 ppl) and remaining garlic to a small bowl. Season with salt and pepper, then stir to combine. Set aside.

Whisk together vinegar, 1/2 tbsp oil and 1/4 tsp sugar (dbl both for 4 ppl) in a medium bowl. Add parsley and tomato. Season with salt and pepper, then stir to combine.
