01 - Preheat oven to 400°F or set grill to medium-high heat.
02 - Pat salmon fillets dry with paper towels. Season both sides with salt and black pepper.
03 - Heat olive oil in a large oven-safe skillet over medium-high heat. Sear salmon, skin-side down, for 2-3 minutes until golden. Flip and cook 1 minute more. Remove salmon to a plate.
04 - In the same skillet, combine pineapple juice, soy sauce, honey, vinegar, garlic, and ginger. Bring to a simmer over medium heat.
05 - Stir in cornstarch slurry and cook, stirring constantly, until glaze thickens, about 1-2 minutes.
06 - Return salmon to skillet, spoon glaze generously over fillets. Transfer skillet to oven and bake for 6-8 minutes, or until salmon is just cooked through and flakes easily with a fork.
07 - Remove from oven. Serve salmon with extra glaze spooned over the top. Garnish with pineapple chunks, green onions, sesame seeds, and lime wedges as desired.
