With salty proscuitto and sweet roasted tomatoes, this tartine recipe from food blogger Beatrice Peltre's book "La Tartine Gourmande" is totally delicious.
Preheat oven to 325 degrees.
In a shallow baking dish, combine garlic, tarragon, muscovado sugar, vinegar, and oil. Add tomatoes and toss to combine; season with salt and pepper. Transfer to oven and bake until soft, 1 to 1 1/2 hours.
Spread each slice of toasted bread with goat cheese; top each with 2 slices prosciutto and tomatoes. Drizzle with oil and sprinkle with fleur de sel. Serve.
