Things change. The venerable A-1 Steak sauce has changed its name to just A-1 because beef's popularity among animal proteins eaten at home has been declining for many years, while chicken consumption is rising.
Did you notice what food people are now calling meat in that sentence? Animal proteins. I absolutely detest that terminology and its showing up everywhere these days. In any event A-1 is plugging the sauce for everything from pork to tofu.
Tofu can't be an animal protein however.
