I find it interesting that so many people like milk. The last time I choked down a glass of (cow's) milk was something like 17 years ago, at a friend's house, to be polite. The last time I remember enjoying milk, I was single-digits in age. I do buy coconut milk and tend to use it as a substitute whenever I can though. I made awesome coconut milk based hot chocolate a few days ago. Oddly, my disgust over milk doesn't stop me from eating cheese, butter, yogurt or ice cream (although I still kinda have to not think about it when I'm eating them or I get the yips).
I don't really know if I have a hands-down favorite dish, but I have several favorite ingredients that usually become something I'll enjoy: Eggs, Salmon, Chicken, Tofu, Bell Peppers, Carrots, Onions and Spinach.
My favorite thing to drink is margaritas, but from a practical standpoint I'm more frequently drinking coffee.
