In a small bowl or measuring cup, whisk together the olive oil, shallot, salt, lemon juice, vinegar, and mustard until evenly blended.
In a large bowl, stir together the lentils, arugula, radishes, endive, cucumber, and dill. Drizzle evenly with the dressing, then toss or stir until all the ingredients are evenly coated. Stir in the walnuts and season with black pepper to taste. Dot the top of the salad with small bits of the cashew cheese (about 1?2 teaspoon each).
Serve the salad right away, or store in an airtight container in the fridge for up to 3 days.
The Best Way to Cook Lentils
Good news: lentils are quicker to prepare from scratch than beans and add great texture and nutrition to dishes. To cook them, start with about 1 cup of red, brown, or Le Puy (green) lentils. Pick out any that are discolored or shriveled. Rinse the lentils under running water, then combine them in a saucepan with 2 1?2 cups of water. Bring the water to a rapid simmer, then reduce to a gentle simmer. Add extra water as needed so that the lentils remain barely submerged. Simmer the lentils for 20 to 30 minutes, until they’re tender but retain some chew. (Red lentils take less time to cook because they’ve been split, so they’ll likely be tender in 20 to 25 minutes.) Drain them, then season with salt and pepper to taste. 1 cup of dry red, brown, or Le Puy lentils will make between 2 and 2 1?4 cups of cooked lentils.
Herbed Cashew Cheese
MAKES ABOUT 1 1?4 CUPS
Nut cheese can be made with almonds, Brazil nuts, macadamia nuts, or pine nuts, but cashews, with their buttery texture and mild taste, are perfectly suited to the task. This cashew cheese, which is soft and spreadable, is infused with herbs for a more complex flavor profile and nutritional yeast for a kick of umami. Spread it on crackers or toast or crumble it over a salad.
Put the cashews in a food processor or blender (preferably a high-speed blender). Add the nutritional yeast, salt, herbes de Provence, pepper, lemon juice, and garlic. Pulse a few times to break the cashews down until they have a wet, coarse, mealy texture.
With the motor running, drizzle in 2 tablespoons of the water. Now it’s time for some kitchen intuition: keep adding water, stopping occasionally to scrape down the sides of the work bowl, until the mixture has a good consistency. It should be similar to thick hummus—a little coarse, but smooth and spreadable. You may not need all of the remaining 2 tablespoons of water. (If using a blender, start on a low speed and gradually increase to high speed as you add the water, using a plunger attachment the entire time to keep the mixture blending.)
Taste and adjust the seasonings as desired. Stored in a covered container in the fridge, the cheese will keep for about 5 days.
