I really like cooking. It can be a real art and you don't even need heat to do it.
Can you explain why you would not need heat to cook?  I am confused.
There are many cooking techniques that vary using a wide variety of traditions. Not everything needs heat to make ceviche.
What is ceviche exactly?  I see it on menus but have never had it.
A seafood dish made of raw fish in citrus, with chili peppers.
Interesting.  What other types of food are there that don't necessarily need heat?
Depends on how you define cooking. Cooking depends on the skill of a person and the education they have.
I sort of get that.  I have very little skill at cooking.  Are there any good books or websites you can recommend to get started?
Not off hand. There are many books in bookstores though. Cooking started so long ago, maybe even 1 million years.
