Step 1

Preheat the grill to medium-high heat; make sure the grill surface is clean. Swipe it with some cooking oil to create a nice slick surface to prevent the meat from sticking. (See notes.)

Step 2

Place the chicken and all of the veggies into a large bowl. Drizzle with the olive oil and season with the Moroccan seasoning. Add a generous pinch of salt and pepper, to taste.

Step 3

Add the fresh herbs, garlic, and the lemon juice. Finally, give everything a good toss to evenly coat the chicken and vegetables. (If you're making this in advance, you can cover the bowl and place it in the fridge for a few hours until you want to start threading your skewers.)

Step 4

Evenly portion out and thread each skewer, alternating between the chicken, onions, and tomatoes.

Step 5

Carefully place the skewers on the grill; grill each side for about 4 minutes (8 minutes total), or until the internal temperature of the chicken is 165º F. (Optional: Grill the other half of the lemon, flesh side down, next to the skewers to give it a slight char, then squeeze the lemon juice over the skewers before serving.)

Step 6

Serve them with mint Greek yogurt sauce!

Step 7

Place all of the spices into a bowl and whisk them together until well blended. Keep the blend sealed tight in a glass jar and store it in a dry, cool place. This recipe makes about 1/4 cup.
