Radicchio raw is bitter. Radicchio grilled will make your heart sing. And it is super easy and fast.
Cut the radicchio into wedges, perhaps quarters. Drizzle and brush olive oil over the radicchio. Salt and pepper each side. Grill on medium heat for about 5-10 minutes per side till the radicchio has browned and shriveled in size.
Hint: Slice grilled radicchio wedges and eat on toast with pesto or parmesan cheese
