It's the same in the U.S., many vegetarians eat fish. That's why I asked. Speaking of marshmallows, have you heard of a sweet snack called "smores?" They're very good! It's most common to make them over a campfire but you can also do it at home in the microwave. You just need graham crackers, chocolate and marshmallows. Or, maybe you can't buy marshmallows in Russia? Here's a photo, and it's vegetarian friendly. :))
