Caption It: What Caused Alex to Make This Face?

Chopped fans know that when it comes to doling out blatantly honest criticism and no-nonsense feedback, Alex Guarnaschelli, a longstanding member of the judges' panel, does it best. She has more than 15 years of experience at the table and knows what winning dishes look and taste like, which means that come Sunday night, Food Network Star finalists will have to cook above and beyond Alex's expectations if they want to impress her. She'll join the Selection Committee as a guest judge during the Chopped-style challenge, overseeing the contestants as they attempt to fuse mystery basket ingredients into camera-worthy meals.

While some contestants may indeed prove to her their culinary chops, others will inevitably disappoint — and then some will simply be so shocking that Alex is rendered nearly speechless at the sight of it. Take a sneak-peek look at the snapshot above from Sunday's all-new episode: Bobby can't help but chuckle as Alex looks on in amazement at what's going on in front of her. What do you think has caused her to make such a face?

Before you tune in this  Sunday at 9pm/8c to find out what causes Alex's stunned face,  we’re challenging you, Star fans, to write your best captions (tastefully appropriate, please) for this moment in the comments below.
