Wash the beets and cut into wedges. Place in an oven safe baking dish, drizzle with a little bit of olive oil and sea salt. Bake in the oven for 30-40 minutes, depending on how large your beets are and how "al-dente" you prefer them. I personally love when they have some chewing resistance left.
Rinse beluga lentils and cook in water and stock cube (if using) for about 20-25 minutes. (Check exact instructions on the once you're using). Then drain from the water.
Place mixed green leaves on a big plate or in a bowl. Add beluga lentils, roasted beets, crumbled goat cheese and walnuts. Drizzle with honey/agave/fiber syrup (if using).
