Wash the potatoes thoroughly, cut into 8 wedges with the skin on, and soak in water. Drain and place in a microwave-safe container, cover loosely with plastic wrap, and microwave at 600W for 3 minutes. Slice the onion into 1cm strips, trim the ends of the green beans and cut diagonally into thirds, and slice the garlic thinly.

Heat olive oil and garlic in a frying pan until fragrant. Add the ground meat and stir-fry over medium heat until the meat changes color. Then, add the potatoes, onion, and green beans, and stir-fry until the onion becomes translucent.
