Step 1: To prepare onions: heat olive oil in large skillet. Add onion slices and saute for 3 minutes. Once onions become slightly opaque, add beer and cook for 30 seconds. Add broth, soy sauce, salt, black pepper, and chili powder. Allow onions to simmer on medium-low for 30-35 minutes until liquid has absorbed and onions are soft. You can make ahead of time and reheat once patties are cooked.
Step 2: Preheat grill for medium high heat.
Step 3: Place ground beef into large bowl. Add minced garlic, 1/3 cup of stout beer, salt, Worcestershire sauce, onion powder, and black pepper to meat. Combine well, but do not over mix.
Step 4: Form into 6-7 oblong patties, a little bigger that the length and width of the marbled rye slices.
Step 5: Place patties onto grill and cook for 5-6 minutes per side.
Step 6: Toward the end of cooking, add 2 Swiss cheese slices to each patty and cook until cheese has melted.
Step 7: Remove from heat and arrange onto toasted rye bread. Top with sauteed onions and remaining bread halves.
