Make the Loco Moco Gravy: Saute mushrooms in butter and olive oil in pan over medium high heat. Once cooked down, add 1 tsp of garlic shallot puree. Cook for one minute. Add wine and reduce by half. Add beef stock and bring to boil. Once it's boiling, add roux to thicken, stirring the whole time to avoid lumps.
To make the Loco Moco Burgers: Form the ground beef into two patties. Season with salt and pepper and grill to your liking.
To prepare the grape tomatoes: Toss with salt and pepper and a little olive oil. Grill on the upper shelf of your BBQ while cooking the burgers, or saute in a pan until softened.
Eggs: Cook sunny side up in an 8-inch omelet pan with a dab of butter to start.
Assemble: Add precooked rice on plate. Top with burger patty, add mushroom gravy, top with eggs and then salt/pepper and chives. Place tomatoes on the side and enjoy!
