You go to the internet!

you google “basic recipe” + something you like to eat, like… chicken and rice.

this could also be something as “stupid” as “how to boil rice”, or similar. super simple stuff! (this was the result i found… its decent enough: https://www.youtube.com/watch?v=HqaAqpS3UWU )

often you can find preperation info on the package and they’re usually just fine.

then you read a few results, pick the one you think is the easiest to understand

then you follow that recipe step by step. Dont use it as “guidelines” or something.

and you do this, with various recipes.

you can also often find videos showing how to cook various things - like chicken - so you can get a more visual feel of how its done. I like some of the basics with babish videos, and some from “Epicurious”, they’ve got some simple ones, such as this:

https://www.youtube.com/watch?v=NTBRThwL-2c (not all their videos are “how to”-basics like this one but they’ve got a few)

Do not be afraid to screw things up. Just try again.

I learned a few basics from my mother when i was a teenager (how to boil potatoes, how do i know when they’re done, etc) and i learned the rest by simply trying…

if in doubt about salt, and “scared” to add too much, just skip it. you can always add it while eating. (again, you will learn. add a bit next time, see how it is. “Salt to taste”!)

then you will eventually be able to cook whatever ingredient.

then its just a question of finding a recipe that contains those ingredients, combine them and boom: you’ve got a whole meal.

as for “meal plans”.

that’s an entirely different topic. i suggest you start with cooking some basics, and really get good at it. make large batches, eat left-overs.
