Peel the potato and slice it thinly. Soak in cold water briefly to remove starch, then drain and dry.

Slice the zucchini thinly as well.

In a bowl, mix the sliced zucchini and potato with pancake mix, cornstarch, water, salt, and pepper until well combined.

Heat a pan over medium heat and add a generous amount of oil. Spoon the mixture onto the pan and shape into pancakes.
