In a large sauté pan, heat the olive oil over medium heat. Add the garlic, peppers, and carrots and lemon slices, and sauté until softened and golden, about 10 minutes. Meanwhile, place the fish in a large bowl and season generously with salt and pepper. Add the chickpeas, and pour the paprika oil and saffron water over them. Use your hands to combine well. Place the salmon and chickpeas over the cooked garlic and carrot mixture and sprinkle with the cilantro on top. If you are preparing this dish ahead of time, you can now cover the pan and store it in the fridge for up to 24 hours until ready to cook.
