Prepare the fenugreek. Separate the stalks from the fenugreek, so you're left with 20 g fresh fenugreek leaves. Wash thoroughly under water. If the leaves are especially bitter, soak in salted water for 10 minutes.
After washing or soaking the fenugreek leaves, drain well and pat dry with a cloth. Roughly chop the leaves (you can leave some whole), along with 60 g cucumber, 60 g tomato, 20 g onion, 3 strands fresh coriander, 2 green finger chillies, and 1 spring onion. Add to a large mixing bowl along with 1 ½ teaspoon lemon juice, and stir to mix the flavours.
If you like, you can add a pinch of salt and sugar to taste right before serving.
Notes
If you would prefer a less spicy gholana, de-seed the chillis.
