Soak your skewers in water before preparing to avoid burning on the pan/grill. To make the chicken, take the chopped pieces of chicken breast and put on the skewers. Place the chicken on a plate.
Whisk the veggie oil, turmeric, chili powder, salt, and pepper in a medium bowl. Pour over the skewers. Turn the skewers around on the plate to coat. Cover and let sit in the fridge for 10 minutes or up to 3 hours.
While the chicken is marinating, make the salad. Cook the couscous according to package directions. While cooking, mix the cucumber, tomato, chopped herbs, and feta in a large bowl. Once the couscous is finished cooking, add to the bowl with the veggies, herbs, and feta. Stir in 1 cup of arugula to wilt.
Make the dressing by whisking olive oil, Greek yogurt, white wine vinegar, salt, pepper, and red pepper flakes until smooth. Pour over the salad and mix to combine. I always keep some extra dressing in the bowl because the couscous seems to absorb the dressing quickly and it's nice to have extra later!
Heat your grill or heat a pan over medium-high heat. Grill the chicken skewers until done, about 15 minutes.
Serve the chicken with the salad and a squeeze of lemon on top! Enjoy.
