Mix together chicken, spices and bread crumbs and form into patties. Spray a skillet with cooking spray and fry burgers until thoroughly cooked. Drain on a paper towel if necessary.
Fry mushrooms in olive oil and 1 teaspoon butter until golden brown.
Fry onions in remaining butter until soft and caramelize.
In a large skillet sprayed with cooking spray place 1 slice bread, 1 slice Swiss, burger, onions and mushrooms. Top with another slice of cheese and bread.
Cook until bread browns and cheese is melted.
