Sauté garlic, onion and spices in a pan until fragrant and onion is just soft.
Add in chopped carrot, sweet potato, lentils and 4 cups water (or low-sodium veggie stock), then allow to simmer for 30-40 minutes or until the lentils are soft and creamy. You may need to add some more water while cooking if it absorbs before lentils and potatoes are soft.
Stir in the lemon juice, peas and fresh coriander, season with salt and pepper, then serve with a big green salad and some avocado.
