These radicchio wedges are wonderful served alongside a grilled entrée.
1-2 heads Luisa radicchio
2-4 tablespoons olive oil
4 teaspoons balsamic vinegar
Coarse sea salt and fresh ground pepper
1. Quarter the radicchio heads lengthwise, leaving the cores intact. Brush the cut sides generously with some of the olive oil, and season with salt and pepper.
2. Preheat grill to medium-high and oil the grill rack.
3. Place the radicchio, cut sides down, on the grill and cook, turning frequently, until browned and tender when pierced at the core with a knife, 8 to 12 minutes total. (Close the lid if using a gas grill.)
4. Transfer the radicchio to a platter and drizzle each piece with about ½ teaspoon olive oil and ½ teaspoon vinegar. Season with additional salt and pepper, if desired.
