Cook the bacon over medium heat until it reaches desired level of crisp. Place it on a plate, chop it, and set aside.
In a large serving bowl, whisk together the cider vinegar, mustard, pepper, yogurt, mayo, and lemon juice until well-combined and creamy.
Place broccoli in a food processor and pulse a few times to give it a rough chop (if you don’t own a food processor, do as I did and thinly slice the broccoli).
Add the broccoli, apple, and bacon to the mixing bowl and toss well until everything is coated in dressing.
