Vibrant, tasty Mediterranean-style black lentils in a bold and spicy green herb sauce with chopped cucumber and feta cheese. Black lentils cook in about 20 minutes and keep well for days in the refrigerator.
Combine all ingredients in a high-speed blender or small food processor until very smooth.
Cook the lentils
Bring 4 cups water to a boil with the salt. Add the lentils and cook 20-25 minutes. Taste-test: They should be tender but not mushy. Drain well and allow to cool to room temperature.
Put the cucumbers, onion and lentils in a serving bowl. Add ⅓ cup of the green sauce and toss gently. Sprinkle the salad with the mint or parsley leaves and crumbled cheese and toss again.
Serve the lentils with additional sauce spooned over.
Notes
Pick through the lentils before cooking to be sure they don't contain an errant stone or twig (lentils are harvested from the ground so it happens sometimes)
