I have to say McDonald's considering they cater towards Vegetarians.
I crave Hot Chocolate and those cheese bites.
I DO need to cut down on Junk food but before becoming a Vegetarian, I did dig the chicken popcorn at KFC. I prefer their fries over McDonald's, they are SO crispy, although they serve for less.
Imo: McDonald's small fries > KFC regular fries when it comes to proportion.
