Bake
Preheat oven to 200oC. Place the ham on a lined baking tray and surround with pears and walnuts. Drizzle everything with maple syrup, and bake for 15 minutes. Remove from the oven and slice ham, then arrange on a plater with pears and walnuts, drizzling with any remaining syrup. Serve Dijon mustard as a side.
Note: If figs are in season, use in place of pears as a change
