Lentil "meat" balls

We have made several versions of lentil "meat" balls, including Dr Fuhrman's, however we prefer rice free, as well as gluten free, grain based flours.
We like this recipe but replaced the GF flour with arrowroot starch. We also added diced celery, add as many anti-inflammatory foods as possible. We baked the balls at 350 for 20-25 minutes, instead of pan frying them. We then freeze them individually and use as needed. The original recipe is from
