Clean the squid, let it drain, and cut it into bite-sized pieces. Marinate the squid with 1 teaspoon of seasoning powder, 1/3 teaspoon of MSG, 1/2 teaspoon of chili sauce, 1 teaspoon of oyster sauce, and 1/4 teaspoon of sugar for 15 minutes to absorb the flavors. Heat a pan on the stove, add a little cooking oil, and sauté the shallots until fragrant. Then add the pineapple and tomato and stir-fry. Continue by adding the squid and stir-fry over high heat to cook the squid without releasing too much water.

Once the squid is cooked, add the chopped onion and celery, season to taste, and then turn off the heat. Serve the stir-fried squid on a plate, sprinkle with a little pepper for aroma, and invite the whole family to enjoy it with rice!
