Pre-heat the oven to 350 degrees F. Line a baking sheet or roasting tray with parchment paper. Toss the walnuts with the honey, maple syrup, cinnamon and salt. Toss well to coat the nuts completely. Pour the nuts on the prepared sheet tray and spread with a spatula into a single layer. Bake the nuts for 12-15 minutes until lightly browned and fragrant. Check on the nuts half way through the cooking time and give them a toss. Remove the nuts from the oven. The glaze will harden as the nuts cool.
