The secret to radicchio is to give it a good soak in ice water, which draws out most of the bitterness, leaving just the yum.
-One to two hours before you want to make this salad, start soaking the radicchio...
-Cut 1 head of radicchio into thin strips.
-Put in a salad spinner or large bowl filled with water and 6-10 ice cubes.
-Let soak, then drain and spin dry before using.
-Add ½ cup lentils and 2 cups water, to a medium sized sauce pan.
-Simmer covered for 20 minutes until lentils are tender.
-Toss lentils with the following:
1½ TBS extra-virgin olive oil
1 TBS red-wine vinegar
The zest and juice from 1 fresh lemon
-Set aside to cool to almost room temperature.
-When the lentils are cool, stir the radicchio into the lentils, then add the following:
1/3 cup crumbled feta cheese
Sea salt and freshly ground black pepper to taste
-Toss well and serve.
