Yes, it looks like cross-contamination from another vat of food -- a stray bean or rehydrated pepper. I'm leaning toward a string bean due to the color, but that could be a distortion from the camera or lighting.
That is a hot red chili pepper. Look up the recipe for orange chicken.
I didn't see the pics but they also use those hot little red peppers in the Kung Pao Chicken, which my wife gets religiously when we dine there.
Thanks for everyone input I am just going to talk to a lawyer and bring it to them to see what they say.
