1 medium onion, finely chopped
2 carrots, peeled and finely chopped
4 garlic cloves, pressed or minced
2 teaspoons ground cumin
2 teaspoons coriander powder
1 teaspoon curry powder
1 can chopped tomatoes
1 cup brown or green lentils
4 cups vegetable broth
2 cups water
1 teaspoon salt, more to taste
Pinch red pepper flakes
Freshly ground black pepper
1 cup chopped fresh spinach, collard greens or kale
Juice of ½ to 1 medium lemon (optional)
1. Add the chopped onion and carrot to 1/3 cup of the broth and cook, stirring often, until the onion has softened and is turning translucent, about 4-5 minutes. Add the garlic, cumin, coriander and curry powder. Cook until fragrant while stirring constantly, about 1-2 mins. Pour in the tomatoes and cook for a few more minutes, stirring often. I like to give the tomatoes a quick spin in the blender before adding them, even chopped tomatoes are quite large and not really soupy. You can do the same with the onion and carrot but you don’t want them totally pureed.
2. Add the lentils, the remaining broth and the water. Add 1 teaspoon salt and a pinch of red pepper flakes. Season generously with freshly ground black pepper. Raise heat and bring the mixture to a boil, then partially cover and simmer for 30-40 minutes, or until the lentils are tender but still hold their shape.
3. Transfer 2 cups of the soup to a blender and purée until smooth. Pour the puréed soup back into the pot and add the chopped greens. Cook for 5 more minutes, or until the greens have softened to your liking. Again I like to put the greens in the blender (separately), it works better than chopping and is sooo much easier.
4. Remove the pot from heat and stir in the juice of half of a lemon. Taste and season with more salt, pepper and lemon juice if you like. Serve immediately. Leftovers will keep well for about 4 days in the fridge, or can be frozen for several months.
You may need to add more broth that listed above, it just depends how thinck you want it. I added at least two more cups to thin it out a little.
The seasonings are optional, you do need some but you can put in whatever you like, the best thing to do is to experiment and see how it tastes.
