I make a version of this but don't use oil,by poaching the mushrooms in a little stock before adding garlic,herbs and salad it makes a lower calorie lunch.A slice of grilled mozzarella is a tasty addition!-16 Jan 2012


The good news is: our fire extinguisher works. I put the mushrooms on the top rack by the broiler, set the timer for four minutes and at three heard a *poof* from the oven. I opened the door to flames shooting out and licking the cabinets above. After our fire extinguisher put out the flames and I'd cleaned up, I finished up the sandwich, and thought it was pretty good. Then my daughter pointed out that the mushrooms I'd just eaten had been sprayed with a fire extinguisher. The poison control center assured me that the f.e. has mostly baking soda inside and that I shouldn't feel any ill effects. But the man laughed at me, so I have to add the caveat to the recipe: leave off the extra baking soda by not letting your 'shrooms catch fire in the first place. Other than the fire marshall warning, these were pretty yummy sammies.-03 Jan 2006

I love portobello mushroom sandwiches and this homemade one rivals the best I have had in my favorite diner. I tweeked the recipe a bit to try and duplicate others I've eaten. I added grilled sweet onions, grilled peeled red peppers, and a slice of provolone. Plus I brushed the bread (NOT hamburger buns) with olive oil and grilled both sides.Very, very good!-04 Jan 2004
