I mean, a burger made mostly out of beans and flavoring, with bacon and cheese, that does at least have less meat in it than the same with a full chuck patty.

And probably most people that have cooked with fatty meat before can tell you that if you fry up some meat in a pan first, and then cook various other foods in the same pan, small amounts of that oil/grease cooked into various other kinds of food can enhance their flavor.

And its almost certainly much better to use basically bean burger... than using ground up newspaper or flour or breadcrumbs as extra mass for the burger... that was not uncommon during the Great Depression.

Call it the 'hybrid' between a standard burger and a fully vegan one, sorta like the hybrid as the intermediary between ICE and EV cars.

It is not gonna be easy to fully snap transition the burger consumption capital of the planet into not using any meat.... baby steps, baby steps.
