Makes two servings.
Wash legumes, add the rest of dal ingredients and cook until done as desired. Heat coconut oil in a pan, add mustard seeds and cumin. Let crackle, add curry leaves, red chillies and garlic. Cook for 30 seconds. Add onion and cook until very soft and brown. Add the rest of the spices and cook for 1 minute. Mix in dal and serve.
Variation: instead of yellow split peas, use split chickpeas. They'll need more time to cook though. Cook all the legumes together for texture - the peas and lentils will get mushy and the chickpeas will stay firm.
