Wash and dry brussels sprouts. Cut off the bottom of each one and discard. With a sharp knife, hold sprout with flat side down on cutting board and slice each sprout as thinly as possible. You can use a mandolin for this, but be careful!
Mince shallot and garlic clove, add to sprouts. Squeeze juice of one lemon over sprouts and drizzle with olive oil and stir until the greens are well-coated. Crack pepper and sea salt on top.
Using a micro-grater, grate cheese on top of salad, toss to combine. Add as much cheese as you fancy.
Optional: toast a few pine nuts and toss them on top.
