In a bowl, whisk honey, rapeseed oil, lemon juice and zest to make a dressing.
Wash the pears, quarter them, remove the cores and cut the pears into narrow wedges. Wash the grapes and cut them in half. Add grapes, walnuts and pear wedges to the bowl for dressing. Clean, wash, pat dry or spin the salads and also place in the bowl. Season with salt and pepper and mix everything together loosely.
Roast the bread slices under the hot grill on both sides until golden brown. Also works in the pan.
Halve the bread slices, cover with the camembert and serve with the salad.
