INSTRUCTIONS

1 For the Onions, mix flour, thyme, salt, pepper and brown sugar in shallow dish. Coat onion slices in flour mixture, being careful to keep slices intact. (Do not separate into rings).
2 Heat oil and butter in heavy-bottom skillet on medium heat until sizzling. Add onion slices. Cook 6 to 8 minutes per side until well browned. Drain excess oil from skillet. Reduce heat to low; add stock. Cover and cook 10 to 12 minutes or until onions are very tender, adding additional stock as need to prevent over browning. Sprinkle top of onion slices evenly with cheese. Cover. Cook just until cheese is melted. Remove cover. Remove from heat. Set aside.
3 For the burgers, mix all ingredients (except rolls) in medium bowl, just until blended. Shape into 4 patties.
4 Grill over medium-high heat until desired doneness. Meanwhile, toast rolls on grill alongside burgers. Serve burgers on toasted rolls, topped with cheesy onion and additional Gruyere, if desired.
