Preheat the oven to 350 degrees F. Spread the goat cheese in equal amounts on the foccacia slices. Drizzle with olive oil and season with salt and pepper. Put the goat cheese croutons on a baking sheet in one layer and put in the oven. Bake for 10 minutes, or until the cheese has begun to melt and the bread is toasted.
In a large bowl, combine the greens, pine nuts, cheese, tomatoes, chives and sprouts and toss. Season with salt and pepper.
In a small bowl, whisk together the vinegar and oil and season with salt and pepper. Drizzle the dressing over the salad and toss. Serve with the goat cheese croutons and garnish with the chive flowers.
