I love me some meat, so much so that you might as well add another "carne" to carnivore.  That said, I am never one to pass up grilled vegetables so when Chef Eric Crowley of LA's highly popular Chef Eric's Culinary Classroom offered to share his recipe for Cheese-Stuffed Portobello Mushroom Burgers I immediately put the ground beef aside and fired up this flavorful vegetarian burger!
