Lentil "Meat"balls

I found a recipe online a few years ago and was able to modify it to make it gluten free for J.  They aren't safe for G because of the lentils and oats, but I'm thinking about possibilities.  Since the original recipe isn't online anymore, I'm posting my recipe here so I don't lose it.

3 cups Cooked Lentils
6 cups Cooked Brown Rice
1 1/2 cups Uncooked Old Fashioned Oats (more if needed)
1 1/2 cups Ground Sunflower Seeds
1 1/2 cups Rice Flour
3/4 cup Soy Sauce
3/4 cup Olive Oil
1/4 cup Lemon Juice
3 t. salt--varies depending on how I prepared the lentils.
3/4 t. nutmeg
3 t. chili powder or taco seasoning

Mix it all up. Preheat oven to 300 degrees.  Roll walnut-sized balls in your hands and place on sprayed or nonstick cookie sheet.  Bake 15 minutes then roll over and bake another 15 minutes.  Let them stand for a few minutes when they come out of the oven to firm up a bit.

These freeze wonderfully and are great for potlucks.  Just pour on a sauce when you are ready to serve.
