Begin by sautéing the diced onion in vegetable oil over medium heat in a large skillet or wok. Cook for about 3 minutes until soft.
Add the minced garlic and diced red bell pepper to the skillet. Cook for an additional 2 minutes until the bell pepper is tender.
Stir in the curry powder, allowing it to cook for about 30 seconds to release its flavor.
Add the cooked rice to the pan, breaking up any clumps, and mix well to combine with the vegetables.
Push the rice mixture to one side of the skillet and add the diced pineapple and peas and carrots to the other side. Sauté for 2-3 minutes until heated through.
Mix the pineapple and vegetables into the rice. Then drizzle soy sauce and fish sauce (if using) over the rice, stirring to combine everything evenly.
Season with salt and pepper to taste. Finally, add the chopped green onions, mixing everything thoroughly for an additional minute.
Remove from heat and transfer to a serving bowl.
Garnish with fresh cilantro and serve with lime wedges on the side for squeezing over the fried rice.
