Cook the rice according to your rice cooker’s instructions. Let it steam for an additional 5-10 minutes before serving.

Preheat a large cast-iron skillet over medium-high heat. In a mixing bowl, combine the ground beef, egg, panko breadcrumbs, Worcestershire sauce, seasoned salt, onion powder, and black pepper. Form the mixture into four equal patties.

Pan-fry the burger patties in the skillet with butter for about 3 minutes per side or until cooked to your desired doneness.

In the same skillet, cook the sliced mushrooms and onion in butter until tender. Add beef stock, Worcestershire sauce, and beef base. Thicken with cornstarch slurry.

In another skillet, melt butter and fry the eggs until the whites are set.

To assemble, place rice on a plate, top with a burger patty, gravy, fried egg, and green onions. Serve hot.
