Seven-Layer Christmas Salad

First, make the candied nuts:
Heat a non-stick skillet over medium heat, and add the walnuts, sugar, and butter to it.
Stirring frequently, cook for 5 minutes. Once sugar starts to melt, make sure to stir constantly.
When all sugar has melted and nuts are coated, transfer to a sheet of parchment paper and use a spatula or spoon to break the nuts apart. Let rest until sugar hardens, 5-7 minutes.
Next, assemble the salad:
In a trifle dish or large clear glass bowl, layer the lettuce along the bottom.
Top with a layer of red onion, followed by a layer of apples, followed by a layer of cranberries.
In a small bowl, whisk together the mayo, sour cream, maple syrup, dijon mustard, and apple cider vinegar. Season to taste with salt and pepper.
Pour dressing over the salad and smooth out the top with a spatula. Cover with plastic wrap and chill until ready to serve, up to 2 days.
When ready to serve, sprinkle gorgonzola, bacon, and candied nuts over the top. Toss to combine and enjoy!
