Toss together first 3 ingredients on a lightly greased rimmed baking sheet. Bake at 450° for 20 minutes or until tomato skins burst and begin to wrinkle (do not stir). Transfer roasted tomatoes to a bowl, scraping accumulated juices into bowl. Stir salt into tomato mixture.
Microwave goat cheese at HIGH 8 to 10 seconds to soften. Smear goat cheese evenly over crostini; top with roasted tomatoes. Serve on a platter; garnish, if desired.
*We found numerous sizes of crostini packages available at large grocery chains. Look for a 6- to 8-oz. container so that you'll have plenty for this recipe. Enjoy any leftovers as croutons over salad greens.
