This fun recipe uses two fiber-rich ingredients that will keep you full all day long. Feel free to use other lentils (green, yellow, red) instead of the black. You can also vary the herbs with parsley, cilantro and so on. The same goes for the topping; try putting some avocado slices, sour cream or cheese on the peppers before serving. Remember, recipes should always be looked at as an inspiration to expand on. Be adventurous and have fun cooking and eating.
