Every year, Weber releases a free grilling booklet. In the old days, you had to call their help line to request it. Now, they're downloadable!
The new one is about healthy grilling:
Weber's Grilling What's Good For You
...and here's a direct link to the PDF itself:
If you like the booklet, save off a copy - they publish a new one every year, and the old ones disappear.
And, while I'm talking about Weber - check out their Weber Nation site - lots of good recipes and technique videos from Jamie Purviance. [Free registration required.]
