1. Preheat oven to 350 degrees Fahrenheit. Rinse and place the salmon slices in a baking dish.
2. Lightly sprinkle each slice with garlic powder.
3. In a small bowl, combine honey, mustard, and mayonnaise. Smear that mixture onto each piece of salmon, then coat each piece liberally with the honey glazed crushed pecans.
4. Bake uncovered for 25-30 minutes. Be careful not to overbake, or salmon will be dry.
