Fried rice is the best use for leftover rice. This version uses shrimp, eggs, carrots and bok choy with tamari and green onion tops, so it is low-FODMAP and gluten-free.
Make the rice a day ahead if you can and chill it uncovered for 1 hour, then covered; cold, dry rice fries without turning mushy.
Heat 1 tsp of the canola oil in a wok or large skillet over medium-high heat. Pour in the beaten eggs and scramble for about 2 minutes until just set. Tip onto a plate.
Add another 1 tsp of oil, turn the heat to high and stir-fry the shrimp until pink and opaque all the way through, about 2 minutes. Tip onto the plate.
Add the rest of the oil, the carrot, bok choy and ginger and stir-fry for 2 minutes over high heat.
Add the cold rice, break up any clumps and press it against the hot pan. Cook for 4 minutes, tossing every minute, until hot and lightly crisp.
Add the tamari, sesame oil, shrimp and eggs and toss for 1 minute until everything is hot.
