Dice the zucchini into 1/2-inch cubes.

Heat sesame oil in a large skillet over high heat. When it shimmers, add the zucchini, salt, sambal oelek, and ginger. Stir-fry until crisp-tender, about 2 minutes. Transfer to a bowl and stir in sesame seeds.

Consider starting with less sambal oelek and adding more once tasted.
