In a large baking dish, add oil, maple syrup, lime zest and juice, ginger, salt and pepper; then whisk with a fork.
Add salmon pieces one by one, coating in marinade on all sides and laying flesh side down. Marinate in the fridge for 30-60 minutes and up to 6 hours. But not longer because acid will start "cooking" the salmon.
Preheat oven to 375 F and line large large baking sheet with parchment paper. Arrange salmon skin side down, leaving room in between and brushing with remaining marinade.
Bake for 15 minutes or until salmon is flaky with a fork. I used wild salmon and it dries out faster. If you use farmed salmon, it may need or can handle longer cook time.
Remove from the oven and serve hot with your favorite side dish and salad.
Notes
Store: Refrigerate in an airtight container and enjoy within 3 days. Cold salmon tastes amazing in healthy salads. Reheat in non-stick skillet on low-medium heat, with a splash of water, covered for a few minutes.
Freeze: Freeze up to 3 months in an airtight container. Thaw in the fridge overnight.
