Preheat the oven to 400°F and line a baking sheet with parchment paper or foil.
Place the salmon filet or filet pieces on the prepared sheet pan and surround with halved tomatoes.
Drizzle olive oil over the salmon and tomatoes and season with salt and pepper.
Sprinkle the minced garlic over the salmon and tomatoes and roast in a preheated oven until the salmon reaches an internal temperature of 145°F. Cooking time for pre-portioned salmon filets should be around 15-20 minutes, and cooking time for one large salmon filet should be closer to 20-25 minutes.
Serve salmon with roasted tomatoes and fresh basil on top of a spring salad mix or alongside rice or pasta.
