Place the egg white in a medium bowl and whisk until frothy. This should take less than a minute.
Add the nuts, vanilla, sugar, and salt. Stir well to evenly and thoroughly coat the nuts.
Spread the nuts onto the cookie sheet and bake for 1 hour, stirring every 20 minutes.
Remove the parchment from the pan and place onto a heat-safe surface and allow the nuts to cool. Nus can be made 2 days in advance, kept in an airtight container.
Make the Caramelized Onions and Beets:
In a large skillet, heat the oil over medium-high heat. Once it is hot, add all the onions.
Lower the heat to medium-low. Stirring occasionally, allow the onions to caramelize. This should take anywhere between 20 and 30 minutes.
Meanwhile, preheat the oven to 400 degrees.
Put all the ingredients for the beets in a gallon zip-top bag (or bowl) and toss to evenly coat.
Spread the beets on a large cookie sheet covered with foil (for easy cleanup) and lightly sprayed with cooking spray.
Roast the beets in the oven for 20 to 25 minutes, or until fork tender.
To assemble:
Scatter the onions onto a plate. Top with the beets. Drizzle with the balsamic vinegar. Sprinkle the nuts, orange zest, and parsley.
Serve warm.
Refrigerate any leftovers in an airtight container for up to 3 days, or freeze in an airtight container for up to 3 months.
Notes
I suggest you use disposable gloves while preparing the beets. They will bleed. Be careful of any cloths/linens or unsealed surfaces that could be stained.You can use golden beets instead of red.The candied walnuts can be made 2 days ahead and kept in an airtight container at room temperature.Be sure you scrub your beets before peeling. Dirt, sand, germs, etc. need to be scrubbed off before you cut off the tops and bottoms and peel.
