In a food processor, combine the first 8 ingredients. Using the chopping blade, blend into a nice puree.
In a large stand mixer, add ground pork, breadcrumbs, eggs, and the mushroom puree
Mix until well combined, approximately 3 minutes.
Form into patties. I used a lid from a large peanut butter jar. Lay plastic wrap over lid and place enough meat to fill lid. This way all burgers are uniform in size and shape.
Barbecue the burgers on a low flame to avoid burning. (The honey will make them burn on a higher flame setting). Grill for approximately 5 minutes on each side, and a temperature of 170F is reached. At this time you can add cheese to the burgers, close lid and turn off heat. Prepare your hamburger buns with you favorite condiments, and add the burger now that cheese is melted.
