Cook the lentils: Add ½ cup red lentils to a saucepan with 2 cups water. Cook until just tender. Do not overcook. Drain well.
Soak the dates (optional): Soak the dates in hot water to cover if not using a high-speed blender. Drain. (see note)
Blend: Transfer the cooked lentils to a blender. Add nondairy milk, Medjool dates, cinnamon, vanilla extract, and banana to the blender. Blend until completely smooth.
Mix and set: Pour into a bowl. Add chia seeds or basil seeds and yogurt. Mix well. Refrigerate for at least 2 to 4 hours, or overnight, until thickened.
Notes
Dates: If not using a high-speed blender, soak the dates first—either in some of the milk from the recipe or in hot water.Find basil seeds here, under 'Shop Healthy Ingredients.'
