Just remove the fish and use the rest of the ingredients. Don't also put a seasonings and a salt.

Like this one:

• Cucumber
• Ginger and Onions
• Soy sauce and Vinegar

Mix it all and put a desired amount of sugar(not to many sugar) or 1 teaspoon full.
and Mix again. :) Hope you'll like the taste madam @bearone! :)

Note: Do not put salt and seasonings. It will make the taste bad.
