1. In a medium saucepan, bring the water to a boil over high heat. Stir in the quinoa and salt and return to a boil. Reduce the heat to low, cover and simmer for 20 minutes, or until all the water is absorbed and the quinoa is tender.
2. Meanwhile, coat a large non-stick frying pan with cooking spray and heat over medium-high heat. Add the onion and cook, stirring, for 3 minutes, or until tender. Stir in the snow peas and garlic and cook for 2 minutes. Add the stock, apricot jam and vinegar and stir for 1 minute to deglaze the pan. Add half of the silverbeet, cover and cook for 3 minutes. Add the remaining silverbeet, cover and cook for 2 minutes, stirring, or until the silverbeet is wilted.
3. Place a quarter of the quinoa on individual plates and top each with a quarter of the vegetable mixture.
