Toast the nuts on a dry pan until they begin to color, then let them cool down.
Remove the outer leaf from the lettuce heads.
Cut the heads in half lengthwise—make sure the leaves stay attached to the core.
Cut the pears in half and remove the cores.

The pears need a little longer time than the lettuce, which just needs a couple of minutes.
Grill the bacon directly on the grill until it is golden and crispy.
Clean the spring onions and grill them until they have colored and become soft.
Arrange the lettuce and pears on a platter.
Shake or whisk all the dressing ingredients together and pour it over the salad.
