Cook the lentils: Rinse lentils in fine mesh strainer. Place in small pot with 1â…“ cups of water and bring to a boil. Reduce heat to low and simmer for about 15-20 minutes, or until tender. Remove from heat and drain excess water if necessary.Add as many lentils and as much spaghetti squash to your bowl as desired. For reference I used about ½ cup cooked lentils, â…” cup spaghetti squash, and half of the medium sweet potato for one bowl. Top with cooked egg, ½ avocado and 2 TBS feta.Store the leftovers in fridge if necessary.
