Preheat oven to 425. Bring a large pot of water to a boil. Add brussel sprouts to the boiling water and cook for about 8 min or until tender but still keep their bright green color.
Drain and transfer to a bowl of ice water. Add little sprinkles of parmesan cheese (about a tsp) in rows on a baking sheet. Pat brussels dry and add to a sheet pan, on top of the parmesan. Using the bottom of a glass, press down on each sprout until they smash and flatten.
Sprinkle each with blue cheese crumbles, salt and pepper. Bake for about 5-8 minutes, or until the sprouts are browned and bubbly. Drizzle with balsamic and serve. Enjoy!

Notes
If you find they are not smashing easily, transfer to a bowl and microwave for a minute or two.
