It's such a pain to shred chicken breast by breast with a fork. To shred your chicken in 30 seconds or less, just put your cooked chicken breasts in the bowl of a large electric mixer(I use a KitchenAid), put on a paddle attachment, lock the mixer and turn it to medium-low speed for 20-30 seconds. The chicken shreds perfectly and it takes almost no time at all!!!
I will never use a fork again!
