@jakedduck1 - That should be good - 20 minutes at 400 should work. I would trust it. But, if you wanted to be scientifically sure, put a meat thermometer into the piece of chicken and make sure it reaches 165 degrees. I realize I have now made this exponentially more difficult - perhaps impossible. But your mission, should you choose to accept it .. is to cook your chicken with your veggies. (Remember Mission Impossible?)

I'm not selling anything here, but I have a thermometer called Thermoworks.
