This was a great way to use the leftover mushrooms from our burgers the other night ...
I just grabbed a flour tortilla, spread mushrooms on half of it. Topped the mushrooms with thinly sliced Gruyere cheese. Threw that all under the grill (broiler) for a couple of minutes til the cheese melted. Folded over the tortilla and that's it.
I loved every bite of it.
I can't wait til the next time we have those mushroom burgers so that I can make this again!
