  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
   1      Head          fresh Witloof endive (1 head per person)
     1/2  cup           Olive oil
   2      Tablespoon    Balsamic vinegar
   1      clove         Garlic

Preparation:

Mash the garlic into a paste and blend with the oil and vinegar. If desired, season lightly with salt and pepper. Slice the heads of endive lengthwise and brush with the oil mixture. Grill about 4 minutes per side, basting occasionally with the oil. (This is a wonderful accompaniment to grilled fish. The recipe will work equally well with radicchio.)
