In a large mixing bowl, whisk together the balsamic vinegar, olive oil, worcestershire sauce, garlic, salt and pepper.
Toss the cut broccoli florets in the marinade mixture. Allow to sit for 15 minutes, tossing every so often to get the flavor into every nook and cranny.
Heat the grill to medium-high heat. Oil a grill basket and set over direct heat. Add the broccoli, tapping off excess marinade and discarding any leftover.
Toss the broccoli every few minutes until the edges are crispy and balsamic vinegar has caramelized, approximately 10-12 minutes.
Remove the heat and spritz with fresh lemon wedges.

Notes
Pro Tip: Get several lemons and cut them in half. Grill, cut side down, to make lovely char marks and serve half of the lemon with the broccoli for a unique and sweeter lemon flavor.
