Menus Get Makeovers As Alternatives To Meat Grow

Restaurants like Buona Beef in Chicago are giving their menus a makeover as diners search for more plant-based options.

Nothing says Chicago like an Italian beef sandwich served up in places like this one — Buona Beef.

These sandwiches are said to have originated in the Windy City in the late 1930s as a way to stretch beef roasts for large gatherings. They are as Chicago as, well, the Chicago Bears.

Except this Italian beef isn't made with beef. It's almost blasphemy, but this edible symbol of the city of big shoulders is made of a plant-based substitute known as seitan.
