Preheat your oven to 400 degrees.
While you're waiting for the oven to preheat do ahead and cook up your bacon. You can do this in a large batch and save 3 pieces for this salad.
Once your oven is preheated cut your sweet potato in half and cook for 30 mins.
Chop the broccoli, shred the Brussels sprouts, and chop the apple.
Put dressing into the bottom of the jar. Add in the apple, broccoli, and Brussels sprouts. Then add in the cooled sweet potato. Next, add in the cooled bacon.
The very last thing is to add in the salad mix you're using to the top of the jar.
When you're ready to eat it dump the contents of the jar into a bowl and combine to coat all of the ingredients in dressing.
