re: OT - Big Green Egg

For hamburgers you just treat it like a regular charcoal grill.

You can get fancy and get a charcoal basket that raises the coals to right under the grates and/or get a GrillGrate setup to better sear. But for cooking burgers, dogs, etc, you can basically use the BGE/any of the Kamado style setups like a Weber Kettle or Walmart charcoal grill.
