Cut zucchini and tofu into bite-sized pieces.
Chop onion, green onion, and garlic.
Heat cooking oil in a pan over medium heat.
Sauté onion and garlic first to release their aroma.
Add zucchini and stir-fry, then add tofu and cook together.
Add seasoning such as chili powder, soy sauce, and salted shrimp, and mix well.
Pour in water or broth and bring to a vigorous boil.
When the broth reduces and thickens, add green onion to finish.
