Mushrooms on Toast

1. Brush the sourdough with a little olive oil and place under a hot grill or in the toaster.
2. Slice the mushrooms and add to a saucepan over a medium heat  with the butter, season with salt and pepper.
3. When the mushrooms are nearly cooked, throw in a dash of Worcester sauce and add the Greek yogurt, stirring through.
4. Once the yogurt is well mixed in place the toast on a plate and pour over the cooked mushrooms.

Serve garnished with some chopped chives or scallions.
