Clean the squid (see note).
Bring a medium pot of water to a rapid boil. Drop the squid in, and cook briefly, about a minute. Quickly remove, and plunge into ice water to stop the cooking and cool.
Cut the squid into thin bite size strips (about ⅓ - inch thick, 2-inch long). Keep it in the fridge to cool.
Prepare the vegetables.
Mix all the sauce ingredients together.
Combine the sauce and squid and mix well. Add the vegetables and toss well. Add more sugar, salt, or and/or vinegar to taste. Serve chilled.
