Cook the quinoa and lentils in about 4 cups of water until lentils are tender, about 20 minutes. Remove from heat and allow to cool slightly.
Preheat the oven to 350F. Lightly oil a baking sheet.
After the quinoa/lentil mixture has cooled enough so that you can handle it easily, drain the excess water and pour the mixture into a large bowl. Add all the remaining ingredients except the gluten and stir well. Mix in the gluten and then use your hands to gently knead the dough for about 5 minutes, to develop the gluten.
Divide the dough in half; then divide each half in half. Then divide each piece in half again until you have 8 pieces. Flatten them so that they’re about 1/2-3/4-inch thick and shape them into rectangles. Put them on the baking sheet and bake for 20 minutes. Turn each one over and bake for another 10-15 minutes, but be careful not to overcook or they will be dry. Serve hot with your choice of gravy (I suggest Impromptu Mushroom Gravy).
