Pre-heat oven to 375F and position the rack in the top third of the oven.
Make the bruschetta by chopping tomatoes into small pieces and combining all bruschetta ingredients in a bowl. Set aside (refrigerate it if you prefer it really cold).
Line a baking sheet with foil for easy clean-up. Place the salmon on the baking sheet and season with garlic powder and salt and pepper. Drizzle about a teaspoon of olive oil on top of the salmon and use a spoon to coat it evenly with the oil. Bake for 10-15 minutes (depending on thickness of fish) until it's cooked through.
When salmon is cooked, take it out of the oven and squeeze the lemon juice on top.
Serve the salmon with the bruschetta sprinkled on top of the salmon. This dish is great with a salad, new potatoes, or rice.
