Related note: There are some good vegan eggs out there to give a try!
If you want something that cooks and bakes like eggs there's stuff you can by like Just Egg
For baking there's a million things you can use that are pretty cheap. For instance, Aquafaba is the leftover water from cooking chickpeas or the water in the can if you buy it canned. Acts like egg whites and can be used as a binder for baking
As long as the aquafaba is salt-free, it makes an awesome substitute for egg whites in mixed drinks. Whiskey sours are absolutely elevated with this substitution.
And this comes from a guy who isn't a vegan. Try it out, folks. You won't regret it.
The problem with the usual egg substitutes is that the corporations have jumped on the price increase there, too. By me, at least, it is still cost prohibitive to get ready-made egg substitutes.
