Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Rinse the chickpeas and pat them thoroughly dry with a paper towel to ensure maximum crispiness.
Toss the dried chickpeas on the baking sheet with half of the olive oil, half of the sea salt, half of the black pepper, and all of the garlic powder.
Roast the chickpeas for 20-25 minutes, shaking the pan halfway through, until they are golden and crunchy.
While the chickpeas roast, season the raw shrimp with the smoked paprika and the remaining sea salt and black pepper.
Heat the remaining olive oil in a non-stick skillet over medium-high heat and sear the shrimp for 2-3 minutes per side until pink and opaque.
In a large bowl, combine the roasted chickpeas and seared shrimp, then drizzle with fresh lemon juice and toss to coat.
Serve the warm chickpea and shrimp mixture over a bed of fresh baby arugula.
