Wash the rice well. The water will be cloudy at first, but after a few washes, it should be clear.
Place rice, water and turmeric and salt to taste in a medium saucepan over high heat. Stir to combine. Bring to the boil. Reduce heat to low. Simmer for 15 minutes or until liquid is absorbed and the rice is tender SEE NOTE 1
Remove from heat and fluff the rice with a fork.
Set aside, covered, for 5 minutes.
While the rice cooks, heat the oil in a deep frying pan over medium heat. Add garlic, red bell peppers and green beans. Cook, stirring occasionally, for 5 minutes or until just tender. Add peas and paprika and cook for 1 minute.
Stir the cooked rice and olives into the pan with the vegetables and toss gently to combine.
Garnish with toasted sesame seeds if using and add coriander and lemon juice. Season with salt and pepper.
Serve with lemon wedges.
