Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them completely dry with a paper towel to ensure they get crunchy.
Toss the chickpeas with 0.5 tbsp of olive oil, smoked paprika, and a pinch of the sea salt.
Roast the chickpeas for 20 to 25 minutes until they are golden and crisp, shaking the pan halfway through.
Season the cod fillets on both sides with the remaining sea salt and black pepper.
Heat the remaining 0.5 tbsp of olive oil in a non-stick skillet over medium-high heat.
Sear the cod for 3 to 4 minutes per side until the exterior is golden and the fish flakes easily with a fork.
In a large bowl, toss the baby spinach and halved cherry tomatoes with the lemon juice.
Divide the salad onto plates, top with the warm roasted chickpeas, and place the cod fillets on top.
Drizzle the tahini over the entire dish before serving for a creamy finish.
