I love my 22.5' Webber kettle. Best yard sale score of my life.
As was said, you can do anything with these things,
Here are my favorites:
- Salmon steaks

- Bread

Just find a recipe you like, and bake with indirect heat. Charcoal choice makes a big difference!
- Steaks
I like to pile the coals in the dead center of the grill for steaks, and literally sear my steaks for maybe two minutes a side, let 'em rest, and serve screaming.
- Potoato wedges
Cut 'em up, season 'em how you want, and then grill them on a well-greased grate over indirect heat (circle method).
- Firm Veggies
Marinade bell peppers, Zucchini, crook-neck Squash, and eggplant in balsamic vinegar with some slat, pepper, basil, olive oil, and brown sugar, throw them on after the potatoes, and grill until they're done to you liking.
- Carne Asada
I like to cut a Sirloin Tip roast into streaks, season with salt, pepper, my southwestern rub (
http://www.smokingmeatforums.com/forum/thread/104939/moose-s-southwestern-rub, shameless plug, sorry!) canola oil, and lime juice. Let that soak in overnight, grill over high-heat until medium-rare, let rest, cut into cubes and serve with tacos. You can adapt this to Tilapia fillets, but cook 'em all the way through, par-cooked Tilapia is too boogery.
You could even bake a pie in one, as long as you manage the temps, and get a perfect "ring of fire" going. I think the burning honey scent of Mesquite charcoal works perfectly for fruit pies, especially peach!
Basically, if you can cook it on a stove, you can cook it on a grill, you just need to get a little creative!
Good luck!
