Want to cook chicken breasts in 20mins? Here’s a quick tip to get it done. Wash your hands ’cause this is hands on.
Place your chicken breast flat on a cutting board.

Clean you hands, cause this requires getting dirty.
You will be cutting it in half lengthwise. Place you hand on top of the chicken. Start cutting with your knife parallel to the board.

Work the knife back and forth being careful to not but your hand. I like to shift my hand towards the end so it’s out of the way of the knife:

Eh Voila, chicken that cooks in 20 mins @ 400f. If you like throw some our BBQ chicken spice.
