Preheat oven to 400 degrees. Add avocado oil onto a baking tray and place the salmon on it with the skin side down.
Heat avocado oil in small sauce pan over medium/low heat and saute the garlic for about a minute. Add balsamic vinegar, honey, salt and pepper and increase the temperature to medium/high for a few second until bubbles form. Reduce temperature to medium and stir continuously for 3 minutes until the sauce has a thicker consistency.
Brush the top and the side of the salmon with 1/2 of the glaze. Bake it in the oven for 10-20 minutes or until the fish is starting to flake.
Remove from the oven and serve on plate. Add rest of the glaze and any garnish of your choice.
