Creating braised leeks and lentils is a straightforward process. Here’s how to do it:

1. Prepare the Leeks: Cut the leeks in half lengthwise, then slice them into 1-inch pieces. Rinse under cold water to remove any dirt.
2. Sauté the Aromatics: In a large pot, heat the olive oil over medium heat. Add the diced onion and garlic, and sauté until softened, about 5 minutes.
3. Add the Leeks: Stir in the leeks and cook for an additional 5-7 minutes, or until they begin to soften.
4. Rinse the Lentils: While the leeks are cooking, rinse the lentils under cold water to remove any debris.
5. Combine Ingredients: Add the rinsed lentils to the pot along with the vegetable or chicken broth, thyme, and bay leaf. Stir to combine.
6. Season: Add salt and pepper to taste, keeping in mind that the broth may already contain salt.
7. Bring to a Boil: Increase the heat to high and bring the mixture to a boil.
8. Reduce Heat and Simmer: Once boiling, reduce the heat to low, cover, and let it simmer for 30-40 minutes, or until the lentils are tender.
9. Remove Bay Leaf: After cooking, remove the bay leaf and adjust the seasoning if necessary.
10. Serve: Ladle the braised leeks and lentils into bowls, garnishing with fresh parsley if desired.
