Both of these big food chains provide vegetarian pizzas in most of the country, but is the cheese used in their pizza free from animal enzyme?
Where I worked they used grated part-skim milk mozzarella. Obviously I can't remember the ingridients of the supplier but pricey mozarella's don't have enzymes whereas cheap mozzarella has enzymes.
I have never been to Malaysia (using logic - they should use the same business tactics as part of their brand), but with my experience from working in Dominos I can state that this type of business tries to save money by cutting the quality of everything - from workers rights to the food itself.
Bear in mind that bread can also have animal derived products (including dough). Here is a comprehensive list to watch out for: http://www.ruf.rice.edu/~veggie/nonveg/watch_out.html
