comments As many Americans on the East Coast finalized dinner plans on Friday, Subway's corporate Twitter account posted a photo of a tuna salad sub sandwich decked with verdant spinach leaves and unbelievably plump tomato slices against a black background. The accompanying caption read, "Keep fishing folks, we'll keep serving 100% wild-caught tuna." It was a not-so-subtle subtweet directed at anyone who had come to doubt if Subway's tuna salad actually contained tuna over the prior week after a lawsuit alleged that the chain's tuna products were instead "made from a mixture of various concoctions."

The plaintiffs, Karen Dhanowa and Nilima Amin, and their attorney repeatedly declined to specify what was found in an analysis of the tuna salad.
