Season salmon fillets with salt and pepper. Set aside.
In a small saucepan, combine pineapple chunks, honey, soy sauce, lime juice, garlic, ginger, and sriracha (if using).
Simmer over medium heat for 5–7 minutes, or until the sauce thickens slightly and pineapple begins to caramelize.
Heat olive oil in a skillet over medium-high heat. Add salmon, skin-side down if applicable, and cook for 4–5 minutes.
Flip the salmon and brush generously with the pineapple honey glaze. Cook another 3–4 minutes, basting as needed, until the salmon is cooked through and flaky.
Spoon extra glaze and pineapple over the top, garnish with fresh cilantro and lime wedges, and serve immediately.
