For the squid, I usually buy the pre-cut and scored frozen variety, then thaw it. Once thawed, rinse it off and then coat with flour (usually 3/4 cup flour mixed with 2 tsp. of garlic powder is enough for a 500 gram bag of squid), and deep fry.
The vegetables can be prepared beforehand or after frying the squid.
You will need:
1/2 of an onion, diced
1 green pepper cut into chunks
1/2 of a red pepper, cut into chunks
5 button mushrooms, halved
Heat a tbsp. of vegetable oil in a large pan or wok. Next add the vegetables and squid and give it a good mix. Add 1 tsp. of soy sauce, 1 tbsp. of hoisin sauce and 2 tsp. oyster sauce. Stir fry to mix everything, then turn off the heat.
It can be served on a plate and garnished with lettuce if you'd like!
You can also sprinkle clean, chopped green onions and cilantro on top just before serving.
