Heat the oil in a large, deep skillet over high heat until smoking.
Add the garlic, ginger and melon and saute for 2 minutes, until the melon has absorbed the oil.
Add 1/4 cup water and saute, stirring occasionally, until it evaporates.
Repeat this process, adding water in 1/4-cup increments, until the melon is tender, 6 to 8 minutes.
Stir in the soy sauce, vinegar and red-pepper flakes and saute for another minute.
Add salt and pepper to taste and serve immediately.
Enjoy!
