Here it is: our most inexpensive dinner ever, and the recipe that started the $5 Foodie experiment. Red lentils, shown here, turn saffron-hued in their brief cooking time, blending with a delicate balance of ginger, onion, garlic, curry, and—surprise—fresh lemon. Fragrant basmati rice complements the Indian flavor profile, though white or brown long-grained rice will be successful too. Lentils, which come in varied hues, are rich in iron and provide 12 grams of protein in each serving. We favor serving them with mint yogurt, crispy onions, or a fresh chutney—or all three.
