Varan recipes range from ultra simple (cooked and mashed toor dal, add salt and turmeric, tadka of cumin seeds in ghee) to more fancy (add tomatoes, green chillies, curry leaves). Simple is great.
Here is the recipe I used for the methi bhaji:
I forgot to add the coriander at the end. I just added the garlic in the beginning instead of at the end, because I didn’t have coconut to do the last step.
It was delicious anyway. Healthy and delicious.
ETA: I think you can use this recipe with any greens: spinach, collards, whatever. Finely chop them, and vary the cooking time appropriately.
