Excellent! I doubled the onions, added just a bit of salt & pepper to the cooked mushrooms, and used & soy cheeses instead of dairy. They were so easy to put together and the taste is out of this world. Definitely a keeper — thanks!

This was really good. I made these for my husband and I the other night because I needed something light for dinner. This was perfect!! I'll definitely make this again!

This is the first recipe I made from this website and it's GREAT! My husband's family are all vegetarian, and love portabellos. They were blown away by this recipe! I cooked the onions for about 45 minutes on medium heat, but they started tasting good after 20. YUM!

Buckled my bf's knees! I used romano cheese instead of parm but it was still great. Easy to make.

Great comfort food! I made it just as described, even with the ketchup (that I was originally skeptical about). I didn't realize it was supposed to make four — but it made two really good sandwiches for us!

Yum, yum, yum! I followed the recipe exactly and it was delicious. I was dubious about the ketchup but it adds a lot to the sandwich. My family and I really enjoyed this one.
