Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Pat the shrimp and chickpeas very dry with a paper towel to ensure they develop a golden-brown sear rather than steaming.
Place the shrimp, chickpeas, sliced bell peppers, and diced zucchini directly on the prepared baking sheet.
Drizzle the olive oil over the mixture and sprinkle evenly with smoked paprika, garlic powder, sea salt, and black pepper.
Toss everything together until well-coated, then spread into a single even layer across the sheet.
Roast for 12 to 15 minutes, or until the shrimp is pink and opaque and the chickpeas are slightly crisp.
While the tray roasts, place the kale in a large serving bowl and massage it with the lemon juice until the leaves soften.
Remove the tray from the oven and transfer the roasted ingredients into the bowl with the kale, tossing gently to combine before serving.
