I thought they sounded weird, too. Then one day last week when I ordered a hotcakes and sausage (I hates eggs!), I was handed a sample of the McGriddle sausage sandwich. It was good. I ended up going back the next day and getting one of those.
I don't think they'd keep in the warmers too long. Most of the sandwiches last for 10 minutes...this one seems like it'd get limp really fast.
I only wished I had syrup to dip it in, LOL!
