First, lay the slices of prosciutto out on a baking sheet. Place in an oven heated to 375 and bake for 10 minutes, until crisp. Then remove from the oven.
While the prosciutto is cooking, slice the brussels sprouts. Slice off the end of each brussels sprout and remove the outer leaves before thinly slicing and pouring into a bowl.
Then julienne the apple, dice the cheese, and add it to the bowl with the brussels sprouts.
Remove the prosciutto from the oven and let it cool while you prepare the dressing.
To make the dressing whisk together the yogurt, ginger, lemon juice, vinegar, and olive oil. Season with salt and pepper to taste.
Add half of the dressing to the brussels sprouts, apples, and cheese, and toss together. Add more dressing if you like, I added about ¾ of the dressing. Top with crumbled prosciutto and serve.
