Mustard-glazed beef burgers with mushrooms

Ingredients:

• 900 g ground beef (15% fat)
• 1/4 cup Dijon mustard
• 3 tablespoons soy sauce
• 1 teaspoon of sugar
• 6 slices Swiss cheese
• 1 tbsp. l. olive oil
• 220 g chopped champignons
• 2 teaspoons fresh thyme leaves and 1 teaspoon dried thyme
• 2 cloves garlic, crushed
• 6 yeast buns

Preparation:

1. Preheat grill to medium heat.
2. Form the ground beef into 6 patties and season with salt and black pepper. To make the glaze, combine the mustard, soy sauce, and sugar in a small bowl.
3. Grill the patties to your desired doneness, 4-5 minutes per side for medium-rare, brushing them with the glaze halfway through. Top with a slice of cheese about a minute before removing from the grill.
4. Meanwhile, heat the olive oil in a large skillet over medium-high heat. Sauté the mushrooms until they begin to soften, about 5 minutes. Add the thyme and garlic and sauté until the mushrooms are tender, about 3 minutes more. Season with salt and pepper to taste.
5. Toast the buns and assemble the burgers with beef patty and mushrooms.
