Flavored with a mixture of soy sauce, Worcestershire, honey and ketchup, then charred to perfection. Perfect summer side dish.
Preheat grill to medium heat. Trim off fibrous bottom half of broccoli stem, then quarter broccoli head into small trees.
In a large bowl, whisk together oil, Worcestershire, soy sauce, ketchup, honey, and garlic. Season with salt, pepper, and red pepper flakes. Add in broccoli and toss to coat. Let sit for 10 minutes.
Place broccoli directly on grill grate. Grill broccoli until knife-tender and slightly charred, flipping every 2 minutes and basting with any remaining sauce, for a total of 8 to 10 minutes.
Sprinkle with Parmesan and more red pepper flakes, if desired. Serve while still warm with lemon wedges.
