Season the salmon fillets with the salt and black pepper. Top with two tbsp of olive oil, juice from 1 lemon and 1 tbsp of lemon zest. Bake the salmon on the top rack for 10 minutes for smaller pieces, or 12-15 minutes for larger, thick pieces. Set under the broiler for 1 minute at the end to crisp.
While the salmon bakes, prepare the peach salad. Slice the stems off of the tomatoes and cut them into wedges.
Slice the peaches in half, remove the pit and slice into wedges. Add the peaches and tomatoes to a bowl with the chopped basil, balsamic, olive oil, lemon juice and salt.
Once the salmon is ready, serve warm topped with the salad.
