Preheat the oven to 400°F / 200°C. Brush the baking dish with a little oil.
Prepare the ingredients: Dry the fillets with a paper towel and season with salt and pepper. Cut the small tomatoes in half and thinly slice the garlic. Deseed the chili and chop it very finely. Juice one lemon. Wash, dry, and cut the second lemon into thin slices.
Mix olive oil, lemon juice, salt, pepper, and oregano in a small bowl.
Assemble the dish: Place the salmon fillets in the baking dish. Arrange the tomatoes around the fish and scatter the garlic on top. Pour the olive oil mixture over everything. Place 1-2 lemon slices on each salmon fillet.
Bake the salmon for 20–25 minutes.
Cook the pasta according to the package instructions while the fish is in the oven. Drain it well.
Finish the dish: Remove the lemon slices and flake the salmon in the baking dish using two forks. Add the drained pasta and toss gently to combine. Adjust the taste with salt and pepper.
