I was pretty happy with the lentil mushroom meatballs adapted from OhMyVeggies, but I wanted a meatier texture. I decided to change around the recipe some more, swapping the mushrooms for tempeh to see if that helped. In the end, I fused together this recipe with the Lentil Mushroom Meatballs recipe.
The resulting meatballs did have a firmer texture, with chewy, nubbly bits that made them seem meatier, somehow.
