set grill on high on one end and off on the other side.
start by mixing bread crumbs and olive oil in a bowl
cut the top of the tomato about a 1/2 inch. keep the top for garnish effect.
pack the newly cut tomato with blue cheese. make sure it's packed on tight so it doesn't spill over on the grill
top the cheese with the bread crumbs
set on the "off side" of the grill, cover and let cook until cheese is starting to melt down the sides, or the tomato starts to blister all around.
i usually serve this with steak instead of potatoes but it could be a meal in itself...
