Slice onions into rings
Once onions are done, transfer them to a plate
Season chicken tenders with salt and peppers
Cook the chicken, turning once, until browned and cooked throughout. About 3 mins per side.
Transfer to the same plate the onions are on, or get a new one!
Put the onions back into the skillet
Sprinkle flour over the onions and stir to coat.
Add broth, milk, and the remaining salt and pepper
Cook until bubbling and thickened, about 2 minutes
Return the chicken and any accumulated juices to the pan and turn to coat
Garnish with fresh chopped parsley, if desired
Enjoy!
