Finely chop the herbs and garlic and mix with 4 tablespoons of olive oil, add the lamb and leave to marinade for a couple of hours in the fridge, covered.
Pre-heat your BBQ over a medium heat for 2-3 minutes. Add the lamb chops and, depending on the thickness, cook on both sides for 2-3 minutes.
At the same time add the asparagus and cook, turning regularly, for 4-5 minutes.
Put the lamb and asparagus onto a serving plate and crumble over the feta before serving
