Preheat your oven to 400°F (200°C) and spray a baking dish with non-stick cooking spray.

In a mixing bowl, combine diced avocado, chopped cherry tomatoes, red onion, and cilantro. Drizzle in lime juice, season with salt and black pepper, mix gently, and refrigerate.

Pat the salmon fillets dry, place them in the baking dish, and brush with a mixture of olive oil, lime juice, lime zest, and chopped cilantro. Sprinkle smoked paprika, salt, and pepper.

Bake the salmon for 10-12 minutes, or until cooked through and flakes easily with a fork.

Garnish the salmon with avocado salsa and serve immediately.
