In a blender, add all the dressing ingredients and process until smooth.
Massage the kale in a large bowl. Add the beets and lentils, tossing gently. When you are ready to serve the salad, gently toss in the avocado, grapes, almonds, and pumpkin seeds and drizzle the dressing in, to taste. (You might not use the whole batch of dressing; save the rest in a covered jar in the fridge.)
