To make the dahl, boil 1 litre water and add the split peas, garlic, ginger, turmeric and bay leaves. Return to the boil, skim off any scum, then cover with a lid and simmer for 45 mins-1 hr, stirring now and then, until it thickens.
Heat the oven to 200C, gas 6. Toss the cauliflower and tomatoes with the oil, cumin, chilli powder, onion and seasoning on a baking tray. Roast for 20 mins.
Check the consistency of the dhal. If it’s a bit runny, remove the pan lid and increase the heat to reduce, stirring well.
Once the split peas are soft and fairly smooth, season well with salt. Serve in a bowl with the cauliflower spooned on top.
Notes
