Mushroom and Beef Hamburgers PT50M https://img5.recipesrun.com/201907/2019/0805/b0/e/143125/300x200x90.jpg These hamburgers — cut through with roasted mushrooms. Make sure to process the mushrooms just until coarsely chopped (about 4 pulses) so they match the texture of the ground beef. The mushroom mixture will look a little wet in the pan at first; take the time to let as much liquid as possible cookout for a richer patty that will hold its shape when seared in the pan. 5 servings Ingredients: Usual burger fixings Sliced tomatoes Lettuce Hamburger buns (preferably whole wheat) 2 tablespoons Canola 1 Egg 1/2 cup Chopped fresh parsley 1/2 teaspoon Worcestershire sauce Freshly ground pepper Salt 1/2 cup Finely chopped onion 1 pound Roasted mushroom base 1 pound Lean ground beef
