Lentil and Rice Summer Salad

In a large saucepan, bring the water, lentils and kosher salt to a boil. Reduce heat to a simmer; cook, covered, for 10 minutes. Meanwhile, rinse rice thoroughly in a fine-mesh strainer until water runs clear. Stir rice into lentils; continue to simmer, covered, for 10 more minutes, or until water is absorbed and rice is tender. Spread rice and lentils out on a large sheet pan to cool for 10 minutes.

Meanwhile, prepare dressing: In a medium serving bowl, whisk together sherry vinegar, mustard and smoked paprika. Gradually drizzle in olive oil, whisking until creamy and emulsified. Stir in cooled rice and lentils, then fold in tomatoes, red onion and basil. Add pepper to taste.
