Form into 4 hamburger patties and wrap in plastic wrap. Place in the refrigerator until flavors have melded, 4 hours to overnight. Heat butter and olive oil in a large skillet over medium heat until melted. Add onions and saute until they begin to caramelize, about 15 minutes, reducing heat to medium-low if they seem to be sizzling too much. Spray a large skillet with cooking spray and heat over medium heat. Place hamburger patties in the skillet and cook for 3 minutes per side, topping each patty with a slice of Cheddar cheese after flipping. Place patties on toasted rye bread. Top with warm onions, Dijon mustard, and remaining bread. Cook's Note: You can use American cheese instead of Cheddar, if preferred.
