Heat 1 tbsp of oil in a sauté pan over medium heat and sauté the onions and 1/2 teaspoon of salt for 4 minutes or until tender. Set aside to cool.
In a mixing bowl, combine the cooled sautéed onions, ground chicken, BBQ sauce, onion powder, garlic powder and remainder of salt and mix. Don't over mix to avoid tough, chewy burgers.
Evenly divide the mixture into 4 pieces for regular sized burgers, or 8 pieces for mini burgers. Shape into patties.
Heat remaining tbsp of oil in a pan and cook the patties for 4-5 minutes (3-4 minutes for sliders) on each side.
Place 1 slice of cheese on each patty during the last minute of cooking and allow to melt.
Place burgers on buns and top with desired accompaniments.

Notes
Don't have ground chicken? You can use ground turkey for this recipe without affecting the flavor profile. Or, if you have chicken breasts on hand, use your food processor to make your own ground chicken.
What's the best BBQ sauce for this recipe? Really, any of your favorite store bought BBQ sauce will work great for this recipe. My only advice is to avoid the ones where it lists corn syrup as one of the first two or three ingredients as they will be a bit too syrupy, sticky and sweet.
Out of onion? No worries! Use whatever you have on hand such as a shallot or red onion. You could even just add some extra onion powder in a pinch. Keep in mind this ingredient adds moisture too, so if you omit it, you may want to add some extra sauce.
