Start by preparing the lentils. Rinse lentils in cool water. Add water, stock and lentils to a pot. Mix and bring to a boil. Once boiled, cover and reduce to a simmer. Let cook until tender. This should take about 15 minutes. They are done when they are tender.
While lentils are cooking, assemble the dressing ingredients (olive oil, apple cider vinegar, honey, sea salt) in a small mason jar. Shake well to mix! You can also mix in a small bowl with a spoon.
Starting with the lettuce, assemble all ingredients in a large salad bowl. When lentils are tender, let cool for a few minutes and then add on top. Dress with the vinaigrette and enjoy it! Option to add sliced avocado on top!
