Great fresh salad for when the pears are in season. Good as a starter or as one of several salads comprising a main meal.
There really aren't any instructions... just mix everything together and serve. You can toast the walnuts in the oven (if it's on) or lightly dry fry them for a few minutes. But keep an eye on them: they go from nicely toasted to completely frazzled in a matter of seconds. The jam adds an interesting twist, but if that doesn't appeal, try sugar or honey instead - the pears give the salad a good hit of sweetness anyway.

A good clump of spinach leaves, rinsed and shredded
1 pear, diced
Handful of walnut pieces, toasted
30g blue cheese, crumbled (optional)
For the dressing:
2 tbs olive oil
1 tbs raspberry jam
1 tbs balsamic or wine vinegar
Salt and pepper to taste
