Combine all the ingredients for the sauce together in a bowl and mix well. Season to taste with salt and pepper.
Trim the asparagus if it has any hard stalky ends. Preheat a griddle pan or a frying pan. Toss the asparagus in the olive oil and then add to the hot griddle pan with a good bit of seasoning. Griddle for a couple of minutes on both sides until they are fairly nicely charred.
Check for seasoning, transfer to a plate and serve with the sauce on the side and a flatbread if you wish.
