Preheat barbecue to medium-high. Slice polenta into 1/2-in. rounds. Lightly brush polenta rounds with oil on each side. Oil grill well and place polenta on grill. Barbecue until polenta is lightly golden and grill marks form, about 6 to 8 min per side. Remove to a serving platter and sprinkle with parmesan and pepper. Cover with foil until ready to serve.

Be sure to use store-bought polenta: it’s firm enough to grill.
