Gaplan Roll

I think there might be some confusion! After conducting research, I couldn't find any evidence of a popular dish or food item commonly found in USA restaurants called "Gaplan Roll." It's possible that it's a misspelling, a variant of a different dish, or a regional specialty.

However, I did find a few possibilities that might be related:

1. Galbi Roll: Galbi is a popular Korean dish that involves grilled short ribs. In some Korean-American restaurants, you might find a "Galbi Roll" which is essentially a Korean-style BBQ beef roll with marinated galbi meat wrapped in a tortilla or flatbread.

2. Philly Roll: A Philly Roll is a type of sushi roll that typically consists of smoked salmon, cream cheese, and cucumber wrapped in rice and nori seaweed. It's a popular dish found in many sushi restaurants across the USA.

3. Spring Roll: Spring rolls are a generic term for a variety of dishes that involve filling a thin dough wrapper with various ingredients, such as vegetables, meat, or shrimp, and deep-frying or steaming them. They're commonly found in Asian cuisine and are sometimes offered in USA restaurants as an appetizer.

If you could provide more context or information about the Gaplan Roll you're referring to, such as where you heard about it or saw it on a menu, I might be able to help you better.
