Thinly slice the cabbage, onion, carrot, and bell pepper. Mince the garlic and ginger.
In a large pan or wok, heat the oil over medium heat. Add the ginger, garlic, and curry leaves. Saute for about a minute. Next, add the onion and cook until soft and translucent, about 3-4 minutes.
Add the curry powder and mix well. Let the spices cook for about a minute.
Add the cabbage, carrot, and bell peppers. Mix well and let it cook for 10-12 minutes. Stir occasionally and cook until the cabbage is tender but still has a little crunch. Add a splash of water if needed to prevent sticking.
Remove from heat and garnish with fresh cilantro and a squeeze of lemon juice. Serve warm with flatbread or rice.
