Preheat your oven to 400°F.
Pat the salmon fillets dry with paper towels and season both sides with salt and pepper.
In a large oven-safe skillet, heat the olive oil over medium-high heat.
Once the oil is hot, place the salmon fillets skin-side down in the skillet. Cook for about 4-5 minutes until the skin is crispy.
Carefully flip the salmon and transfer the skillet to the preheated oven. Bake for an additional 5-7 minutes, or until the salmon is cooked through and flakes easily with a fork.
While the salmon is baking, prepare the chickpea ragu. In a separate saucepan over medium heat, add the chickpeas, tomato paste, smoked paprika, cumin, and red pepper flakes. Stir to combine and cook for about 2 minutes until fragrant.
Add the diced tomatoes and vegetable broth to the chickpea mixture. Bring to a simmer and cook for about 10 minutes, allowing the flavors to meld and the sauce to thicken slightly.
Stir in the lemon juice and chopped parsley just before serving.
Serve the crispy salmon on a bed of spicy chickpea ragu, garnished with additional parsley if desired.
