Thai
Italian
Chinese/American
My absolute favorite food is Thai, especially the curries! In fact the only curries I've liked have been Thai. And all the food I've tried has been fabulous. My favorite restaurant is Indochine, found in Tacoma, Washington though recently I found a fantastic (if not as good) Thai restaurant in Reno. I can't wait to go again!
Italian was my favorite until I encountered Thai food. I love pasta's and bread and Olive Garden is still one of my favorite restaurants.
Chinese food is just a classic. Nothing like going to a Chinese restaurant, drinking the cups of tea, figuring out your Chinese sign yet once again and all those yummy noodle dishes and sticky rice, mmm. American is on the list because I love BBQ's and Burgers and Steak!
I think Religions/Denonimations can definitely have a distinctive food culture. Growing up as a Seventh Day Adventist, my family was one of the more liberal Adventists. The health message is almost as important to the Church as is the Prophetic side of things (not trying to get into religious debate here, just saying what was important in my Church). I would say that at least 50-60 % (if not more, maybe I'm guesstimating too low) of Adventists are Vegetarians. And about 40 % of those are Vegans. Most of the churches I went to had purely Vegetarian potlucks (I'm assuming most of you know what those are) with a smattering of Vegan dishes thrown in. These were the mostly "white", mid-conservative churches that my parents preferred. Some of the more cultural churches (predominantly black or spanish or Samoan/Tongan) served mostly meat dishes. Anyways, that is probably only interesting to me.
My family ate both meat and vegetarian dishes regularly. However, we did so according to the Clean foods in Leviticus, avoiding any of the Unclean meats. I find that prejudice (I don't really consider it a belief on my part anymore) still affects me to this day. I find shrimp and ham completely unappealing (to name some). The only weakness I really have is for pepperoni and that is strictly on pizza.
Anyways I'll stop rambling other than to say that Haystacks is a pretty common, widespread Adventist food that you can find in our churches everywhere.
