Looks tasty.
My kids grew up with broccoli and now they'll select in in restaurants for the side dish.
Not sure how or why ... we tried various veggies, usually frozen, and I think frozen broccoli florets work as well as fresh broccoli does, maybe that's why. I usually steam them inside on the stove to save time/effort/success, but every once in a while, when I'm able to baby sit and STIR them on a grill like that, I will, and the extra smokes is special.
