Instead of using bits of radicchio to punch up a salad, try searing it in a hot pan to make a vegetable side dish. Searing brings out a little bit of sweetness from this bracing vegetable.
Uncoated pans made of other materials like anodized aluminum or stainless steel might also work well. Non-stick pans are not recommended because high heat is used.
