Here is the answer (there are two possible answers):

First, the more common answer is:

「いくら」 (fish roe)

This is because 「いくら」 is pronounced “ikura” and is “fish roe”, which is a possible topping on sushi.
But also 「いくら」　(ikura) is the Japanese for “What is the price?”

Another possible answer is:
「はまち」 (Yellowtail Tuna)

This is also a possible answer to the riddle because 「はまち」 is another possible sushi topping, and it’s pronounced hamachi which sounds similar (with a Japanese pronunciation) to the English phrase “How much?“
