Combine all the seasoning sauce in a bowl and set aside.
Pre heat a skillet over medium high heat until well heated. Add a generous amount (2 to 3 Tbsp) of cooking oil and add onions and green onions. Stir for 1-2 mins until fragrant. The oil may splash, so watch out for that.
Add the remaining vegetables. Stir over medium high heat until the cabbage is slightly wilted (about 2 mins).
Add the squid and the seasoning sauce. Stir evenly with the vegetables. Reduce the heat to medium and cover the skillet with a lid and cook further for about 5 mins or until the squid is cooked. Stir occasionally.
Remove from the heat. Add the sesame oil and stir around quickly.
Serve the cooked squid and vegetables on a bowl of rice. If adding, garnish with sesame seeds and green onion and top up with a fried egg.
