Tonight - grilled pepperoni and onion pizza - sorry Corky no pickles. Side salad.

Anyone here have good ideas for seasoning a rib roast (choice not prime if it matters)? One of these days soon I'm going to sous vide the one in my freezer and then probably sear quickly on the grill. But I've only helped someone with an oven-baked rib roast before, never made one on my own.
