Start by cooking the French green lentils according to package instructions. Once tender but still firm, drain and let cool.
Preheat oven to 400°F (200°C). Toss cauliflower florets with olive oil, ground turmeric, and a pinch of salt. Spread on a baking sheet and roast 20-25 minutes until golden and crispy.
In a blender or food processor, combine cilantro, lime juice, serrano chiles, and a drizzle of olive oil. Blend until smooth and season with salt to taste.
In a large mixing bowl, combine cooked lentils, roasted cauliflower, chopped spinach, paneer cubes, minced garlic, grated ginger, ground cumin, ground cardamom, and sea salt.
Pour cilantro lime dressing over salad and toss gently until well coated.
Season salad with freshly ground black pepper and additional salt if needed. Drizzle with olive oil for extra richness.
Serve warm or chilled. Enjoy immediately or store for later.
