Instructions

  1. Step 1: Heat 2 tbsp sesame oil in a large skillet over medium-high heat until shimmering. Add 3 minced garlic cloves and sauté for 30 seconds until fragrant but not browned.
  2. Step 2: Add 300 g peeled and sliced Okinawan purple sweet potato rounds and stir-fry for 5 minutes, stirring frequently, until they start to soften and edges get lightly browned.
  3. Step 3: Add 150 g thinly sliced bitter melon, 2 tbsp soy sauce, 1 tbsp mirin, 1/2 tsp salt, and 1/4 tsp freshly ground black pepper. Continue stir-frying for another 5 minutes until bitter melon is tender but retains some crunch.
  4. Step 4: Remove from heat and sprinkle 1 tbsp toasted sesame seeds over the stir-fry before serving warm as a colorful vegetable side.
