Step 1

Preheat an outdoor grill for medium-high heat and lightly oil the grate.

Step 2

Combine cauliflower florets, Buffalo wing sauce, ranch, and olive oil in a large bowl. Stir until evenly combined.

Step 3

Pull out an extra-long length of aluminum foil and fold it in half so you've got a double layer. Place cauliflower mixture in the center, then pull over one side, folding the edges to seal. Then fold the remaining two edges. Don't seal the packet too tightly; you want to leave some room for the steam to expand.

Step 4

Place foil packet directly on the grate and grill for 15 minutes.
