What is the average weight of a sushi slice?

There is no single "average" weight for a sushi slice. It depends on many factors like:

* Type of sushi: Nigiri (single piece of fish on rice) will be different from maki (rolled sushi) and sashimi (slices of raw fish).

* Size of the fish/ingredient: A large piece of tuna will weigh more than a small piece of cucumber.

* Amount of rice: Some sushi chefs use more rice than others.

* Specific ingredients: Different fillings and toppings will contribute to the overall weight.

However, as a rough estimate:

* Nigiri: Individual slices can range from 15-30 grams (0.5-1 ounce) depending on the type of fish used.

* Maki: Each roll is typically cut into 6-8 pieces, and a whole roll can weigh between 100-200 grams (3.5-7 ounces).

Remember, these are just general estimations. The actual weight of a sushi slice will vary depending on the specific sushi you are eating.
