You won’t miss the meat in these burgers! It calls for feta cheese, but you could use another kind. To clean the mushrooms he recommends using a special brush or a paper towel. I find that I can use just my thumb to do this. I briefly put the mushroom in water & then use my thumb to brush the top layer off the mushroom cap. I use a peeling motion, like I’m using a vegetable peeler, & start at the edge of the cap working toward the top center. Works for me.
Top with lettuce, tomato, onions, pickles, cole slaw, whatever you like. I love a generous helping of guacamole!Serve with baked beans, corn on the cob, green salad, potato salad, sweet potato fries, etc. Great for casual meals with family and friends.
