Where’s the beef? It’s not in the latest sandwich offering from Buona. The iconic Chicago purveyor of beef sandwiches is adding a plant-based Italian beefless sandwich to its restaurant menu starting Monday.

The vegetarian- and vegan-friendly seitan meat sandwich mimics its classic Original Buona Beef counterpart, except for the main ingredient. Everything from the vegetable-based gravy and bread to Buona’s iconic giardiniera was already vegan. The new sandwich retails for $7.99 (available only in the 7-inch size) and is now on the menu at all 24 Buona locations for a limited time.
