Grilled Radicchio Pesto

Preheat grill to medium.

Brush radicchio halves on all sides with 1 tablespoon oil. Grill the radicchio, turning once, until lightly charred and softened, 3 to 4 minutes per side. When cool enough to handle, remove the core and coarsely chop the leaves.

Place the chopped radicchio, cheese, anchovies, garlic, vinegar and pepper in a food processor. Pulse until coarsely chopped, scraping down the sides once or twice. With the motor running, add the remaining 1/3 cup oil and continue to process until well combined, scraping down the sides once or twice.
