• Step 1: Cook the rice according to package instructions. Fluff with a fork and set aside.
• Step 2: In a large skillet or wok, heat the olive oil over medium-high heat. Add the diced onion and sauté for 3-4 minutes, until translucent.
• Step 3: Add the minced garlic and cubed chicken to the skillet. Cook, stirring occasionally, for 5-7 minutes, until the chicken is lightly browned and cooked through.
• Step 4: Pour the reserved pineapple juice into the skillet and add the soy sauce, ground ginger, and red pepper flakes (if using). Stir to combine and let the sauce simmer for 2-3 minutes.
• Step 5: Add the drained pineapple chunks to the skillet and gently fold them into the chicken and sauce mixture. Season with salt and black pepper to taste.
• Step 6: Serve the pineapple chicken mixture over the cooked rice, garnishing with chopped green onions or cilantro, if desired.
