Microwave potato on high for 3 minutes or until fork-tender; let cool slightly. Peel and shred using the largest holes of the box grater; set aside.
Scatter zucchini and onion onto a clean kitchen towel. Roll into the log and squeeze to remove excess moisture. Combine zucchini, onion, potato, flour, salt and pepper.
In a skillet, heat half of the oil over medium-high heat; cook rounded tablespoonfuls (15 mL) of zucchini mixture in batches, turning once and adding more oil as needed, for 3 or 4 minutes or until golden brown and crispy.
Remove from skillet; place on paper–towel–lined plates. Serve warm with Blue Dragon Sweet Chili Sauce for dipping.
