Next year I plan on going to Vietnam for two weeks with around 20 other people. I have a severe allergy to peanuts and tree nuts (though I only have a reaction when I eat them,). How common is the use of peanuts and tree nuts in Vietnam? I normally don't carry an Epi Pen with me because I am just always careful about where and what I eat and know all the restaurants that use peanut oil. I know I will have to bring some Epi Pens with me on the trip, but is it easy to avoid foods that include nuts or are cooked in peanut oil? My main concern is that I am going to be spending the entire trip worrying about everything I eat instead of actually enjoying my time in Vietnam. Also are there any common or widely accessible dishes served in the country that don't use peanuts or tree nuts that could be my "go to" dishes when eating out?
