Preheat the oven to 400° F.200C and line a baking sheet with parchment paper. Place the walnuts in a large bowl. Toss with the egg white. Sprinkle with the brown sugar substitute, cinnamon, and salt. Stir to combine.
Step 2
Arrange the walnuts in a single layer in the prepared pan. Bake for 6 to 8 minutes, until the nuts are just starting to brown.
Step 3
Remove the pan from the oven, and allow the nuts to sit for 10 minutes in the pan until the sugar hardens.
