Cooking is the art of preparing foo for consumption.
That was so well put! What else about cooking do you know?
Thank you! Well techniques and ingredients vary quite a bit from grilling over an open fire to using electric stoves. There are an innumerable amount of ways to cook with or without heat.
That sounds great! What are the different ways one might cook without heat?
Well see that depends on the skill and type of training that a cook has.
Interesting! What about vegan chefs? 
Unfortunately I don't know a whole lot about vegan chefs, I'm sorry. What I can tell you though is preparing food with heat is an activity unique to humans!
It is, I never really thought about that.  What other things can you tell me about cooking as a hobbie?
There are various types of ovens that can be used for baking, another form of cooking.
Which kinds? I have a conventional one... I didn't know there were others.
