Cut the sweet potato into bite-sized pieces, soak in water, and drain. Place in a microwave-safe container, cover loosely with plastic wrap, and microwave at 600W for 3 minutes.

Thinly slice the onion and garlic. Cut the sausages diagonally in half.

Heat olive oil and garlic in a frying pan over low heat until fragrant.

Add the sausages, sweet potato, and onion to the pan. Stir-fry until the onion becomes tender.
