Heat 2 teaspoons olive oil in a large saucepan set over medium heat.
Add the onion and garlic, and cook, stirring occasionally, until onions are translucent, 4 to 5 minutes.
Add the remaining 1 teaspoon olive oil, mushrooms, pepper and sage. Cook, stirring occasionally, until the mushrooms are tender, about 5 minutes. Stir in the balsamic vinegar.
Add the vegetable broth to the onions and mushrooms. Stir well. Bring the mixture to a boil over medium-high heat.
Add the orzo and cook until the orzo is almost al dente.
Add the Swiss chard, cover the saucepan and cook for about 3 minutes, or until the Swiss chard is wilted. Serve it up!
