For the sauce, combine A.1., vinegar, Worcestershire, pepper, garlic, salt, and butter. Bring to a simmer and remove from heat to allow to cool.

Spread:
Cap, core and cut the Jalapeños into rings.
Cook until soft, allow to cool. 
Brown breakfast sausage and cook bacon until crispy.
Combine sausage, bacon, jalapeños and cream cheese and cool.
Form your 80/20 burger patties and season liberally. 
Place on the grill.
After your first turn, begin to apply the sauce. 
Spread your bacon, sausage, jalapeño cream cheese mixture onto both sides of your toasted bun. 
Lay your cooked burger between the layers on the grill one last time to allow the spreaded mixture to melt.
