Dressing: Whisk together all Honey Mustard Dressing ingredients until smooth. Taste and adjust seasonings as needed.
Prep: Chop broccoli into florets, then set on a large sheet of aluminum foil. Throw on the garlic (peeled but not minced) and drizzle with oil. Cover with more foil and pinch together to form a sealed pouch.
Grill: Set broccoli pouch flat on a heated grill set to medium/high heat. Cook for 5 minutes, flip, then cook another 5 minutes. Broccoli should be tender with a few slightly charred spots.
Assemble: Roughly chop broccoli into bite-sized pieces, then mix together with cranberries, feta, and almonds in a large bowl. Toss with half of the Honey Mustard Dressing, taste, and add more dressing as desired.
