This is the sauce I basted on my steak after I cooked it:
Pineapple teriyaki sauce
1/2 cup pineapple juice
1/2 cup soy sauce
3 tsp brown sugar
1 tsp rice vinegar
1 tsp ground ginger
2 gloves minced garlic
Pinch of red pepper flakes
2 tbsp cold water
1 tbsp cornstarch
Combine all ingredients besides the cold water and cornstarch into a saucepan and bring to a boil. Add in slurry made with cornstarch and water. Once thickened remove from heat.
I added sautéed peppers and onions, jerk seasoning and red pepper flakes to my rice.
I patted my pineapple dry and grilled on each side about 3-4 minutes over high heat on my grill
