A blend of mushrooms and veal create patties that are cooked to perfection and topped with a slice of Swiss cheese. The delicious patty is placed between two Portabella mushroom caps which serve as the bun. Add condiments and additional toppings to taste.
In a medium sized bowl, mix the veal, chopped mushrooms, bread crumbs, milk, garlic powder, onion powder, salt, black pepper and chopped parsley to incorporate.
Form the meat mixture in 4-6 burgers that consist of or 6 ounces per patties.
Take the stems off the mushroom and use them as part of the chopped mushrooms. Using a table spoon, scrape out the gills from underneath the mushrooms and discard. Combine all the ingredients for the Portabella mushrooms and toss lightly.
Pre-heat the grill; when hot, grill each mushroom until tender, about 6 minutes and reserve warm. Add the burgers one at time and brown for 2-3 minutes; turn the burgers over and repeat the browning process, making sure the burgers reach an internal temperature of 155°F.
Add one slice of Swiss cheese to the burgers.
Place one Portabella mushroom on a serving platter, add a burger and place the second mushroom on top. Serve immediately.
