Lentils and Mushrooms

Cook lentils until soft but still retain shape, about 20 minutes. Drain well. 

In a large sauté pan over medium heat, sauté mushrooms, zucchini, red bell pepper and garlic in olive oil until just softened. Set aside.

To make sauce, whisk together vinegar, mustard and extra-virgin olive oil in a small bowl.

In a large bowl, toss together lentils, vegetables, sauce and green onions and season to taste with black pepper. Serve warm or chilled.
