Creamy coconut
Swap 1 cup of water for coconut milk and add a thumb of grated ginger with the garlic. This adds richness and a subtly sweet, tropical note that pairs beautifully with the spices.
high proteinHigh-protein
Stir in 1 cup of cooked shredded chicken or 200g of cubed firm tofu after simmering. Boosts protein without altering the core lentil base.

Water-sauté the onion and garlic by adding 2 tablespoons of water instead of olive oil, and reduce oil to 1 teaspoon for blooming spices. Cuts fat while keeping flavor.
