Lentil "meatballs" over mashed sweet potatoes with a dollop of sweet onion gravy.
The lentil mixture I made up the day before. Make sure the lentils are quite soft and mash more than half of them to help the balls hold together. I didn't end up using any flour (gf or otherwise). The potatoes took about 10 minutes, the meatballs about 5 (cook time, after prep).
Second day, I cooked them closer to med-low for longer, as I waited for the rice, creating a crispier, more meat-like consistency, and they held their heat better to boot.
