I tried this for the first time a few weeks ago. The lovely wife loved the outcome, and required me to stock up for the summer.
4lbs Mozarella and 4lbs Colby-Jack (Walmart brand). 2lb bricks cut into quarters.
A lit briquette, a couple of unlit briquettes and a small chunk of Cherry. I added a couple of bottles of ice under the cheese because it's nearly 60 degrees today.
