Usually I do a big cook for friends in Indiana every 4th of July, but this year I was in Boston instead and had to improvise. Fortunately I found a Weber 22" in my parents basement and decided to throw an impromptu BBQ for about 15 people. I've been doing a lot of Argentinian style grilling lately, and decided to take things in that direction.
I ended up buying some lump charcoal at Whole Foods (AKA Cowboy) and also stumbled across this:

It was basically pressed hockey pucks of wood scraps cut in half. It burned surprisingly well, and the smoke had a nice aroma to it. I used it for roasting and grilling and it worked very nicely. It burned VERY hot. I'd be interested in finding something similar around here and giving it a try for a true low and slow smoking.
I started out by roasting some peppers

Next up was a chuck roast, rubbed with veal salt, black pepper, guajillo powder, and EVOO.

I roasted it at 300-350 for a couple hours
After that I grilled up some sirloin tips, boned beef short ribs, and onions. After cooling I sliced everything up and topped with a garlic/parsley chimichurri.

It all turned out very well (and satisfied my cooking jones during my week of vacation).
