Whisk the pineapple juice, soy sauce, ketchup, brown sugar, ginger, and garlic. Pour half over the chicken and marinate 10+ minutes; save the rest.
Start the rice.
Simmer the reserved sauce in a small pot 5 minutes until it thickens into a glaze.
Grill the chicken over medium heat 6-7 minutes per side, basting with glaze in the last few minutes, until 175°F. Grill thick pineapple slices 2 minutes per side alongside.
Slice the chicken and serve over rice with grilled pineapple and green onions.
