Heat 1 tablespoon oil in a stir-fry pan over medium-high heat. Add beef and stir-fry, breaking beef up into small pieces. Add rice wine, soy sauce and oyster sauce. Cook until beef is completely cooked and no liquid remains in the pan, about 5 minutes.
Remove beef from pan. Set aside.
Wipe pan clean and add remaining 1 tablespoon oil. Heat over medium-high heat and add garlic, cook until fragrant, about 30 seconds.
Add red, yellow and serrano peppers, cook until crisp-tender, about 1 minute. Add pickled long beans, sugar and rice wine; cook for 1 – 2 minutes. Return ground beef to pan and toss to combine.
Serve hot, garnished with green onions.
If pickled long beans are not available, it is ok to substitute store-bought giardiniera (Italian pickled vegetables).
