Bbq Portabella

Clean off the portabella cap, and cut stem close to cap, chop stem. Gently heat the olive oil in a saute pan, then add the peppers, onion, and stem. Saute all together until just tender. Set the peppers aside for a moment and use a pastry brush dipped in the flavored olive oil in the bottom of the pan to oil the portabella caps. With the top side of the cap down, put all the peppers, etc. on the underside (up), transfer to the grill and cook for about 3-4 minutes. Put the cheese onto of the peppers, and grill until melted.
