How to Make It
Preheat oven to 400°F.
Place squash, oil, 1/4 teaspoon salt, and pepper in a bowl; toss to combine. Spread mixture in a single layer on a foil-lined baking sheet. Bake at 400°F for 28 to 30 minutes, tossing once halfway through.
While squash bakes, place lentils in a medium saucepan. Cover with water to 3 inches above lentils; bring to a boil. Reduce heat, and simmer 20 minutes or until lentils are tender. Drain. Stir in remaining 1/4 teaspoon salt, cumin, and red wine vinegar. Let stand 10 minutes.
