A new Subway restaurant lawsuit argues that the chain’s tuna isn’t actually tuna. Two Bay Area residents, Karen Dhanowa and Nilima Amin, are plaintiffs in the complaint according to The Washington Post. Basically, their representation is claiming that the fish is more of “a mixture of various concoctions that do not constitute tuna, yet have been blended together by defendants to imitate the appearance of tuna,” according to the complaint. They’ve gone so far as to have independent lab tests on “multiple samples” taken from select Subways in California. It’s a wild story and another weird instance where someone is claiming that a menu item isn’t what the restaurant says it is. However, the sandwich chain isn’t taking those kinds of accusations lightly. They’re trying not to have this entire thing heat up and make a big stink. Check out what the complaint says about this tuna situation down below.

Sandwich artist: Welcome to Subway! What kind of sandwich do you want?

Rando: Umm. I’ll take the halibut.

Sandwich artist: Sorry we don’t do halibut.

Rando: Sea bass?

Sandwich artist: Nope.

Rando: Fine I’ll take the tuna. pic.twitter.com/PTaXfZHLRy
