Green bean and ricotta three-grain risotto

Method

1. Melt a knob of butter in a large pan, then add the chopped onion and sweat for 10 minutes or until soft. Add the garlic and cook for another minute, then stir through the grains.
2. Turn up the heat, add the white wine, simmer for another 2 minutes or until all the liquid has been absorbed, then add a splash of stock. Keep adding a little more stock as each addition is absorbed, stirring all the time, until the grains are tender but still have a bit of bite.
3. Meanwhile, bring a pan of water to the boil and cook the beans for 3 minutes or until tender. Drain and refresh under cold water.
4. When the grains are cooked, stir in the beans, ricotta, lemon zest and the remaining butter. Season well and serve in ?bowls with a squeeze of lemon juice and a sprinkle of grated parmesan.
