Sri Lankan Gotu Kola Salad or Gotukola Sambol is my favorite salad of all time. I can eat this every day and I'd still crave more. Try it once and I promise you, you're going to LOVE this salad, even if you're a salad hater.
Wash and clean Gotu kola. Dry them off using a salad spinner. Or leave them in a colander to drain all water out. Make the leaves and stalks into a bundle and slice them thinly. Make sure to use a sharp knife so you won't bruise the leaves. (You can cut them into thicker slices too)
Into a bowl, add coconut, onions, green chili, black pepper, salt, Maldive fish chips, and lime juice. Mix very well with your fingers (wear gloves).
Then add chopped Gotu kola leaves and tomato. Mix gently but thoroughly without bruising the leaves. Adjust salt and lime to your taste.
