So tomorrow i leave for a 4 day trip. I'll be staying in cabins and they have a cafeteria which is where we will eat everyday. They only serve foods with meat and dairy. We contacted the place and they said that they will make a vegan version of whatever everyone else is eating. I'm concerned that it won't be vegan or that it will end up just being lettuce. I don't like salad, especially since a vegan salad at most places would just be lettuce. I will not have access to a fridge or any way of cooking food. I can only bring 1 small duffel bag so I'm very limited on space but I need enough pre made vegan food that doesn't need to be refrigerated to last 4 days. What can I bring?
