Spicy Chicken Legs and Cauliflower Couscous with Cherries, Pistachios, and Mint

In a large bowl, whisk together rice vinegar, orange juice, Sriracha, garlic, soy sauce, honey, crushed red pepper, and 2 tablespoons olive oil until combined. Add chicken legs; let marinate 15 minutes. In a food processor fitted with a metal blade, pulse cauliflower florets until they reach the size of couscous. Heat 2 tablespoons olive oil in a large skillet and add cauliflower couscous. Cook until softened, 3 to 4 minutes. Season with salt and pepper. Transfer to a paper towel-lined plate and set aside. Meanwhile, preheat oven to 400 degrees F. Heat a lightly-oiled grill pan over medium-high heat. Remove chicken from marinade and season with salt and pepper. Grill chicken 4 minutes per side to get a nice char on the outside, then place pan in oven to finish cooking for 10 minutes or until it reaches an internal temperature of 165 degrees F. Let rest 5 minutes. In a large bowl, stir together cauliflower couscous, cherries, mint, pistachios, lemon zest, and remaining 1 tablespoon olive oil. Season with salt and pepper and garnish with mint. Serve chicken legs with couscous and lemon wedges.
