Heat pan to medium heat with olive oil and toss in the sliced onion along with the Lee Kum Kee Panda Brand Sweet Soy Sauce. Mix together and let cook down and caramelize for 30 minutes. If onions start to burn, turn heat down to low.
Once onions are nice and caramelized, remove from pan and place into a bowl.
Slice the bagels in half and toast them.
