    We make these all the time. Only thing we add is a splash of Frank's Red Hot (chicken) wing sauce. Makes it really tasty. Yum!

    These were in my family's opinion, a total waste of otherwise good ingredients. they were mushy and did not taste good at all.

    To shoppingaddicctAZ: It doesn't change the taste. The only thing that I would change is, when marinating, only rest the top of the mushroom in the marinade. If you marinate the gill side, they tend to get too mushy for my taste. Doing this does not affect the amont of flavor from the marinade. Good Luck!

    These sound great and I want to try them!  I love grilled portobellos!  I have a question, though.  In some recipes it says to de-gill the mushrooms; this one does not.  Does it make any difference in the taste to remove the gills?Lorraine
