Prepare your lentils according to the packet instructions.
While your lentils are cooking, dice all your vegetables roughly and add them to a large saucepan. Saute them with a splash of water under tender.
Add spices, evaporated milk, tomato paste and lemon juice and simmer so the flavours develop.
Once your lentils are cooked, add them to the saucepan and stir until evenly distributed.
Serve with rice or as is. Can be stored in the fridge for a few days or divided among containers and frozen.
