For real the alternatives that exist are good now, and useful as a pipeline while learning better recipes.

Unless you are strapped for cash, do yourself a favor and start switching over everything to easy replacement products much sooner rather than later.
It is one of those things where, in hindsight, you'll be glad that you did it. It takes time finding what products you like, and there is lots of variation between brands.
Some of the cheap stuff is really good but you have to find it first.

If you get to a place where consuming any animal products makes you severely hate yourself, is better to already know what food there is that you like.
Much easier to sate or resist the craving for blood and milk when you already know something that tastes better or scratches the same itch.

I legit have an old bottle of iron pills in my cabinet, for some previous medical thing. (don't take too many the body cannot excrete it)
It makes me happy sometimes, how to be a bloodmouth without killing things... i swear half of carnism is just that (subconscious) feeling of power and dominance gets people hard.

It can be good to have like backup meals, so if cooking something new goes to shit, you can at least have soup or something that's previously frozen.
