Answer:
The type of irony found in this excerpt is: situational irony.
Step-by-step explanation:
When the author leads the reader to believe a certain event will take place only to change the outcome unexpectedly, we have what is called situational irony.
In this case, the author makes a point of describing Chef Kylie's dishes in detail. Meat is the main - if not the only - ingredient in all of the dishes mentioned. That is why readers are surprised once they learn the chef is actually a vegetarian. It is quite ironic - or at least, unexpected -, as a matter of fact, for a vegetarian chef to be cooking so much meat. We know vegetarians and vegans tend to be strong advocates of the rights of animals. Therefore, what we have here is an example of situational irony.
