  • 1 tsp Sugar

  • 1 lb Ground Beef lean
  • 1 tsp Sea salt
  • ½ tsp Garlic powder
  • ½ tsp Paprika
  • ¼ tsp Onion powder
  • 4 Slices Swiss cheese

Fried eggs

  • 4 Eggs
  • 1 Tbsp Butter
  • Salt & pepper To taste

Sauce

  • Cup Mayonnaise
  • 2 Tbsp Barbecue sauce
  • 1 tsp Worcestershire sauce
  • ½ tsp Tabasco sauce

Other

  • 4 Hamburger buns
  • Arugula

Instructions
 

For the onions and mushrooms

  • Cut the onion in half. Remove outer layers, slice the tops off. Then slice about ¼“ thick starting from the top. Discard root piece.
  • Wipe the mushrooms clean with a damp paper towel. Slice into about ¼“ slices
  • Preheat a medium size frying pan over high heat until hot. Add butter, melt. Add the onions and sugar. Reduce heat to medium and sauté for about 5-7 minutes or until the onions get a brown color to them.
  • Add the mushrooms, soy sauce and pepper. Sauté another 5 minutes or until the mushrooms are softened and browned. (Keep the heat high enough so most the water from the mushrooms evaporates)

For the patties

  • Preheat grill on high heat
  • Crumble the beef into a mixing bowl. Add the seasonings. Carefully mix together, taking care not to overwork the beef or it will become tough.
  • Divide into 4 portions about 4 oz each. Shape into patties, making them slightly bigger then your buns.
  • Place patties on the grill, reduce heat to medium to medium/high. Grill covered for 2-3 minutes per side. Reduce heat to low, top each patty with a slice of cheese. Let melt (about 1 minute). Remove patties, keep covered until ready to use.
  • To toast the buns on the grill return the grill to high heat. Place buns cut side down on the grill for a couple minutes or until nice and browned.

For the eggs

  • Heat a large frying pan until hot. Melt the butter and distribute evenly across the bottom of the pan. Carefully crack your eggs into the pan. Sprinkle with salt and pepper.
  • Reduce heat to low. Cover and cook for 1-3 minutes or until the whites are set and the yolks are done to your liking. These burgers are best with a yolk that is thickened but still runny.

Finally for assembling!

  • It goes like this. Bun, sauce, mushrooms and onions, patty, egg, arugula, sauce, bun. Or however you decide ;) Good job! Now go enjoy all your hard work!
