Preheat oven to 400 F and line a 9x13-inch baking pan with aluminum foil.
Use 8 rings of pineapple to form two rows on the pan.
Place salmon on top of pineapple rings.
Dice up remaining pineapple and place in medium sized bowl. Add melted butter, teriyaki, lemon juice, honey, and minced garlic to bowl. Stir well to combine.
Pour mixture over salmon.
Bake for 35-40 minutes on the center rack of the oven. Salmon should reach an internal temp of 145 F when done.
Pineapple Avocado Salsa
Combine pineapple, avocados, red onion, cherry tomatoes and cilantro in a medium sized bowl.
In a small bowl combine lemon juice and chili powder. Pour mixture over salsa. Stir to combine then store in the fridge until salmon is ready.
Salmon Tacos
When salmon is cooked, cut into 2-3-inch slices and place on serving plate.
Warm taco shells by wrapping them in aluminum foil and baking 2-3 minutes at 400 degrees.
Top each taco shell with 1-2 pieces of salmon and a heaping spoonful of salsa. Drizzle with creamy siracha sauce and garnish with fresh cilantro.
