It is grilling season in Ventura County. Some of you grill all year round, but I know it's time to start seriously grilling when the radicchio and romaine lettuce is prime. We've been grilling greens every night. The technique is simple. Grill it hot, grill it thickly sliced, grill it fast. Once it's off the fire, add some type of cheese salt, oil, and vinegar. I like Ojai olive oil, Monte Grappa's balsamic reduction (they'll sell you some if you ask) and St. Agur blue cheese (find it at Westridge Market.)
Here's a grilled radicchio recipe from Simply Recipes and a short video on the technique for grilling romaine lettuce. Get creative and apply this technique to any veggie in the CSA box. You'll be grilling everything.
