Meanwhile, heat about 1.5 tablespoons olive oil in a medium oven-proof skillet over medium heat.

Remove from the heat – and place the pan in the preheated oven. Bake 5-8 minutes, or to your liking (will depend on thickness and size of your salmon).
To serve - place a salmon fillet on each plate and drizzle with balsamic glaze.
