What each ingredient does
- Soft cheese
- Provides a creamy, spreadable base that holds the sandwich filling together.
- Chopped walnuts
- Adds crunch and a nutty flavor that contrasts with the soft cheese.
- Butter
- Adds fat and richness to the bread and helps keep it from soaking up moisture from the filling.
- Lettuce
- Adds moisture and a fresh, crisp texture to the sandwich.
