In a soup pot, heat the olive oil over medium-high heat. Add the carrots, onion, garlic, sprigs of thyme and rosemary and sauté until the onion is soft, about 4-5 minutes. Add the tomatoes and keep cooking for 3-4 minutes, until the tomato is saucy. Add the lentils and the liquid smoke and stir well. Add the broth and bring to a boil. Reduce the heat to a simmer, season to taste with sea salt and pepper, and let cook, stirring occasionally until the lentils are cooked, about 20 minutes. Cooking time may vary depending on the type of lentils. Ensure you are testing for doneness as you cook, and remove from the heat before the lentils are mushy. Adjust seasonings if necessary, remove from the heat, and serve. Bon appétit!
