In a large bowl, season the ground beef with fajita seasoning, parsley and green onions and mix well. After the seasonings are fully mixed in with the ground beef, form it into patties. In a medium sized grill pan, cook the beef patties until they are browned throughout.
Heat olive oil in a separate saute pan and add mushrooms, stirring frequently. Add chicken stock, salt and pepper to the pan and let the mushrooms simmer for approximately 5 minutes. Grill the buns open-faced on a grill pan, just until they begin to brown.
On a plate, rest the buns open-faced and place a burger patty on top of each bun. Finish off each burger with a slice of Brie and a spoonful of sauteed mushrooms.
Serve with Pepper Slaw and Sweet Potato Sticks.
Mix all of the ingredients together in a large bowl. Stir everything together until the flavors are incorporated and then set aside.
Peel the sweet potatoes and cut them into matchsticks. Place a heavy skillet over high heat. Add about 1-inch of oil to the skillet and heat. Add the potatoes and fry until crisp. Remove the pieces once they are crispy and place them on a paper towel. Salt, to taste.
