Thinly slice the brussels sprouts with a sharp knife. I like to cut the end off, slice in half lengthwise, then thinly slice the halves.
Remove the pits from the cherries using a cherry pitter. Then quarter the cherries.
On a large platter, or in a bowl, combine the shaved brussels sprouts, sliced pear, sliced cherries, blue cheese crumbles, and pistachios.
Prepare the dressing
In a small mason jar or measuring cup, combine the olive oil, lemon juice, honey, dijon mustard, onion powder, salt and pepper. Stir well, or put the lif on and shake vigorously until combined.
Pour the dressing over the salad and toss to combine.
Serve immediately.
