Preheat your oven to 400°F (200°C).
In a small bowl, mix olive oil, minced garlic, rosemary, thyme, salt, and pepper.
Rub the mixture generously over the lamb chops.
Heat a skillet over medium-high heat and sear the lamb chops for 3 minutes on each side.
Transfer the skillet to the preheated oven and roast for 10 minutes.
Remove the lamb chops from the oven and let them rest for 5 minutes.
In the same skillet, add the mixed vegetables and sauté until tender.
Stir in balsamic vinegar and Dijon mustard into the vegetables.
Plate the lamb chops alongside the sautéed vegetables.
Serve with creamy mashed potatoes for a complete meal.
