Stovetop Barbecued Lentils
Quick and easy, this barbecue favorite is absolutely addictive. A great make-ahead dish for a potluck or a picnic, it's loaded with fiber.
Yield: 2 quarts; 8 (1/2-cup) servings

Ingredients:
1 tablespoon olive oil
1 cup chopped red onion
1 tablespoon minced garlic
2 teaspoons chili powder
1 teaspoon mustard powder
2 cups fat-free chicken or vegetable broth
3/4 cup tomato sauce
3 tablespoons balsamic vinegar
1 tablespoon Dijon mustard
2 tablespoons agave nectar or dark honey
1 1/2 cups brown lentils, rinsed
Salt and pepper to taste

Instructions:
Heat olive oil in a 2-quart saucepan over medium heat. Add onion and sauté until softened and translucent, about 3 minutes. Add garlic and spices and sauté until fragrant, about 1 minute; do not brown garlic.
Add broth, tomato sauce, vinegar, mustard, agave nectar, and lentils, stir well, and bring to a boil. Reduce heat to low, cover, and simmer until lentils are tender, but intact, about 30 minutes. Lentil cooking times vary. If necessary, add an additional 1/4 cup water and simmer for 5 minutes longer if lentils are not tender. Season with salt and pepper.
