Last night's winner Aaron McCargo, Jr., who will premiere his new show "Big Daddy's House" this Sunday on the Food Network, pinpointed his I-Knew-I-Was-a-Serious-Eater-When moment this afternoon on the phone: "I was four, and my family started passing out rice, peas, and pearl onions... they give me one chicken leg, and I said to myself, they got to be joking. When I get older, I'm going to cook a whole chicken and eat it myself."
