Absolutely delicious! The sauce is amazing and the arugula is great tasting with this burger.
Instead of using a whole mushroom cap, I used the thick cut mushroom slices, same kind, and it was even better. This is a very good recipe!

Simple, but so delicious! I'm chronically ill, so easy recipes are a must for me. This recipe was so quick and easy, still packing so much flavor. I always love Paula's recipes,this is one of my favorites. To add to my delight, it's not as bad for you as a hamburger is. Will definitely make again, this weekend to be exact. Give this one a try!
