Trim leaks and wash real well. Drop into boiling salted water. Boil for 10 to 15 minutes until white parts are tender. Remove from water and plunge into an ice water bath. Dry with paper towels, slice in half lengthwise. Make a dressing of 1/4 cup olive oil, 1 clove garlic pressed and 1 T red wine vinegar. Sprinkle dressing over leeks. Sprinkle with fresh ground black pepper and freshly grated Parmesan.
One thing you could do different is after slicing in half lengthwise, cut into bite sized pieces.
