I actually use the LBE for other foods more often than pizza: my wife only likes the pan-fried Sicilian type, so usually it's just me and the kid eating the Neopolitan.
Great things to make on the LBE:
Sirloin steak @ 800F, in cast iron pan with OO- perfect char and tenderness; side of potatoes (wrap in foil, place on hearth during heat-up), or steak fries (frozen kind, in pan with a little oil)
Cordon Chicken Bleu in puff pastry & salad with fire-roasted croutons
Fresh bread boules for NE clam chowder or cream of crab soup - perfect on a winter night
hamburgers (of course) I'll take a picture next time I make some. I use a small cooking grate on a broiler pan for that.
Balmer Pit Beef! Basically a highly-spiced dry rub roast, cooked next to charcoal. I place charcoal in one of the charcoal baskets, and cook the roast on a grate over a pan. Slice super-thin, serve with horseradish, onions and mayo on Kaiser rolls: delicious!
Cedar-planked fish - salmon is the standard, but tuna or swordfish is even better. I've got a huge pile of cedar shims left over from building the house - they are perfect to cook on.
I really like making the kebabs, and I think that will be a big hit at our next cookout. Even the kids can get into spearing the vegetables, and once they taste the smoky char, they won't whine about eating them!
