In a soup pot, heat the grapeseed oil to medium-high heat. Add the onions, fennel, carrots, garlic, mushrooms and thyme. Sauté until softened, about 5-7 minutes. Add the lentils, the vegetable broth, the tamari or soy sauce, and the apple cider vinegar. Bring to a boil, lower the heat and let simmer about 20 minutes, or until the lentils are cooked and tender. Remove from the heat, remove the thyme sprigs and garnish with the tarragon. Taste, adjust sea salt and pepper, if desired, and serve. Bon appétit!
