In a small bowl, whisk together apple cider vinegar, honey, and garlic cloves. Set aside.
Place a medium/large nonstick pan over medium-high heat. Add avocado oil. Pat salmon dry and sprinkle with salt and garlic powder on top. Once hot, add the salmon filets meat-side down to the greased pan. Sear for about 5 minutes, until golden. Flip over on to the skin side and let sear for 2 minutes. Add the apple cider vinegar mixture to the pan and let that come to a low boil. Cook for 3-4 more minutes before removing from heat.
