Prepare the Roasted Chickpeas: Preheat your oven to 375°F (190°C) and line a large baking tray with parchment paper. After draining and rinsing the chickpeas, pat them thoroughly dry with paper towels, removing any loose skins — the drier they are, the crispier the result. In a mixing bowl, toss the chickpeas with olive oil, garlic powder, lemon zest, salt, and pepper until evenly coated. Spread them in a single layer on the baking tray. Roast for 45 to 50 minutes, stirring halfway through to ensure even crispiness. When golden and crunchy, remove from oven and sprinkle Parmesan cheese over the hot chickpeas, letting it melt slightly.
Make the Caesar Dressing: While the chickpeas roast, whisk together olive oil, Greek yogurt, Parmesan cheese, lemon juice, Dijon mustard, Worcestershire sauce, garlic powder, salt, and pepper in a bowl until smooth. If the dressing is too thick, add a teaspoon or two of water until it reaches your preferred consistency. Chill the dressing in the fridge until serving.
Massage the Kale: Remove the tough stems from the kale and chop the leaves into bite-sized pieces. Place the kale in a large bowl and drizzle with olive oil, lemon juice, and a pinch of salt. Using your fingertips, massage the kale gently for 3 to 5 minutes — this softens the leaves and reduces bitterness, making them tender and more enjoyable to eat.
Assemble the Salad: Combine the massaged kale, Romaine lettuce, and Parmesan cheese in a large serving bowl. Toss with the prepared Caesar dressing to coat evenly. Plate the salad and top generously with the warm Parmesan roasted chickpeas for a satisfying crunch.
