Start small - like a fried egg. All you need is a pan, a spatula, some butter/oil and an egg itself.

Then upgrade to an omlette.

Then omlette du fromage.

Then a pirate’s eye (egg in a slice of bread/bagel). Add some dill.

Boil some potatoes.

Mash some boiled potatoes.

Rice is simple - just boil it for some time.

Essentially - you’ll learn by doing. Just don’t start with making your own bread and you’ll be fine.
