1. Mix the garlic, mustard, and vinegar in a small bowl. Whisk in olive oil and water. Add herbs, and season with salt and pepper.
2. Combine blanched and raw vegetables in a bowl. Add olive oil and toss to coat, season with salt and pepper. Grill vegetables over medium heat, turning frequently, until slightly charred and just tender, about 5-7 minutes.
3. Place salad blend in a large bowl; add half the dressing and gently toss to coat. Arrange salad on a serving platter or on individual plates and top with grilled vegetables; drizzle with remaining dressing. Sprinkle with goat cheese and more fresh herbs, if desired.
