For the Dressing:
Combine the lentils, garlic, bay leaf, onion, carrot and water in a large saucepan or Dutch oven. Bring to a boil. Add salt to taste (1 to 2 teaspoons), reduce the heat to low, cover and simmer 35 to 45 minutes until the lentils are tender. Remove from the heat and discard the onion, carrot, garlic cloves and bay leaf. Drain, reserving the liquid.
Place lentils in a large bowl.
In a small bowl, whisk together the Sicilian Lemon White Balsamic, Dijon mustard, shallots, and salt. Whisk in the Roasted Pistachio Oil and 2 to 4 tablespoons of the liquid from the lentils. Stir into the lentils. Add the parsley, cucumber, red pepper, pistachios and ground pepper. Garnish with a parsley leaf. Serve warm or allow lentils to cool before serving.
