Question: what is the difference between vegetarian refried beans and regular refried beans?
Answer: If it says "vegetarian" on the label, than most likely yes. "Vegetarian" would mean there are no meat products in it (many brands of refried beans contain animal lard) but there's always a chance there might be an milk product in there, so check the label. As for "fat-free" refried beans, this gets more tricky.
