1) For the sauce: Put the garlic and olive oil in a small microwave-safe bowl and microwave on HIGH until the garlic is golden, 1 to 2 minutes. Stir in the lime juice, coriander, and salt and set aside until ready to serve.
2) For the vegetables: Pour 2.5cm or more of water in a wok or skillet and bring to a boil over medium-high heat. Place the vegetables in a bamboo or collapsible steamer. Set the steamer over the boiling water, cover, and cook for 5 to 8 minutes, or just until the vegetables are crisp tender. Serve warm or at room temperature with the sauce.
