In a large bowl, combine the brussels sprouts, apple, chives, feta, and pecans.
In a medium jar, shake together the olive oil, apple cider vinegar, lemon juice, hot honey, Dijon mustard, and generous pinches of salt and pepper. Adjust to taste.
Pour the dressing over the salad and toss to combine. Store in an airtight container in the fridge for up to 4 days.
