In a bowl, combine the halved tomatoes, chiffonade basil, minced garlic, a large pinch of kosher salt and black pepper, and 1/2 tablespoon olive oil; toss gently and set the bruschetta mixture aside.
Pat the salmon fillets dry with paper towels and season all over with kosher salt, black pepper, the garlic powder, and Italian seasoning.
Heat 1 tablespoon olive oil in a large skillet over medium heat until shimmering.
Place the salmon in the skillet skin-side down (if applicable) in a single layer and cook until golden on the bottom, about 2 to 3 minutes.
Gently flip the fillets and cook until the second side is golden and the salmon flakes easily with a fork, about 2 to 4 more minutes depending on thickness.
Once cooked through, remove the salmon from the pan, drizzle each fillet with balsamic glaze, then top with a generous spoonful of the tomato-basil bruschetta and serve immediately.
