How to Make It
Bring 3 cups water and lentils to a boil in a medium saucepan over medium-high. Cover, reduce heat to low, and simmer, stirring occasionally, until lentils have split and are mushy, about 30 minutes. Drain and spread in an even layer on a small baking sheet; chill 30 minutes.
Process lentils, tahini, lemon juice, oil, tomato paste, garlic, salt, paprika, and cumin in a food processor until smooth, about 30 seconds, stopping to scrape down sides as needed. Spoon into a serving bowl. If desired, garnish with parsley and olive oil. Serve with crudités or pita wedges.
