Wild Mushroom with Caramelized Onion on Polenta Squares

Wild mushroom with carmelized onion on polenta squaresA wonderful, savory experience. This is another of the few canapés that I made for my initial catering experience. This pairs well with a full bodied red wine. I’m no sommelier, but I’m a sucker for a good Malbec. This is another inspiration from pinterest, but once again I felt it needed a few tweaks. In particular because everything had to be gluten free.
