Preheat your grill or grill pan over medium-high heat, and preheat your oven to 425°F for roasting the broccoli.
In a small bowl, mix the olive oil, lemon juice, chopped fresh rosemary, thyme, salt, and pepper.
Brush the lamb chops evenly with the herb mixture, then let them marinate for about 10 minutes.
Toss the broccoli florets with a dash of olive oil, salt, and pepper and spread on a baking sheet.
Roast the broccoli in the oven for 15-20 minutes until they are crispy on the edges.
Grill the lamb chops for about 4-5 minutes per side for medium-rare, or adjust the time according to your preferred doneness.
Warm the cooked quinoa if needed and plate alongside the lamb chops and roasted broccoli.
Garnish with a sprinkle of fresh herbs and serve immediately.
