Smucker’s and Trader Joe’s enter a legal battle over the PB&J sandwich.

Smucker’s is suing the grocery chain in federal court, accusing Trader Joe’s of copying its Uncrustables sandwiches.

The suit alleges Trader Joe’s competing round, crustless, peanut butter and jelly sandwiches are too similar to Smucker’s.

They also say the packaging is a direct copy.
