Find a baking sheet that fits your grill or if you have it, a vegetable roasting pan made for grilling.
Trim cauliflower and cut into florets.
Toss with a drizzle of oil and season with salt and pepper.
Roast over medium high heat until tender and slightly golden and charred.
Meanwhile, in a large sauce pan on the grill, melt the vegan margarine. Add the hot sauce, water and sugar. Stir until combined.
Toss the cauliflower in the sauce pan and using tongs, place back onto the grill pan. Roast for another 10 minutes.
NOTE: This recipe is formatted for grilling and tailgating, but you could certainly oven roast the cauliflower if you are at home.
Combine all ingredients to prepare the vegan ranch dressing.
Serve with lots of celery sticks and a side of the vegan ranch.

THIS RECIPE SERVES ABOUT 3 PEOPLE COMFORTABLY. YOU SHOULD HAVE ENOUGH BUFFALO SAUCE FOR TWO WHOLE CAULIFLOWER, BUT WILL NEED TO DOUBLE THE VEGAN RANCH RECIPE IF DOING SO.
