For a vegetarian option, substitute the squid with shiitake mushrooms or firm tofu, ensuring to press out excess water before dicing and sautéing. Adjust the amount of tapioca flour in the teriyaki sauce to achieve your preferred thickness. A thicker sauce will cling better to the potato bites. Experiment with different toppings! Sesame seeds, green onions, or a sprinkle of chili flakes can add exciting flavor dimensions.
