Gently mix hamburger and sausage together until mixed and then set aside. Don’t over work the meat – just gently mix it all together with your finger tips.
In a small bowl, mix salt, pepper, thyme, onion and garlic powders together until well blended.
Add the spice mix and the steak sauce to the meat mixture and gently mix together. Do not over mix the meat or it will become tough and chewy.
Pat into 3-4 inch diameter patties. Place a thumbprint dimple in the center.
Using a brush or your hands, rub each patty with olive oil and place patties on a dinner plate.
Sprinkle each side of the burger with a pinch of salt and pepper
Put plate in the refrigerator for at least 10 minutes to rest
Preheat pan or grill to medium heat
Cook to desired inner temp. I think 3-4 mins per side is about right for a pink in the center burger
Rest on a clean plate once removed from the heat for 5 minutes, tent a piece of aluminum foil over the top.
