Oh Lord! Now you have the foodie in on this. Out of all the things I've had, I'm going to have to be cheesey here and say my favorite meals are all things my Mom and Grandma cook.
Cabbage rolls, wiskey glazed corned beef, pozole, chicken penne with tomato vodka cream cauce, and fried oysters...YUMMY! Makes me home-sick and hungry just thinking about it.
As for snack I love homemade elk and bison jerky, cashews and the classic poor-college kids food; Instant Ramen Noodles.
