The recipe for this savory side dish comes from Norm Matthews of Junction City, Kansas.
In a 10-inch skillet, heat olive oil over medium heat. Add onions; reduce heat to medium-low. Cook, stirring occasionally, until onions are golden and caramelized, 35 to 40 minutes. Season with coarse salt and ground pepper.
Meanwhile, in a 3-quart saucepan, bring 5 cups water to a boil. Stir in brown lentils; reduce heat to a simmer. Cook until tender, 10 to 12 minutes. Drain; rinse pan.
Return lentils to pan; add long-grain rice and vegetable broth. Bring to a boil; reduce to a simmer. Cook until rice is tender and has absorbed liquid, 10 to 12 minutes. Season with salt and pepper. Scatter onions on pilaf.
