Place oil and garlic in a Dutch oven; turn heat on medium and cook until garlic starts to sizzle and turn golden. Add tomatoes and olives, bring to a simmer, reduce heat to medium-low, and continue to simmer until sauce is thick enough to mound on a spoon, 10 to12 minutes.
About half hour from serving, adjust oven rack to center position and heat oven to 450 degrees. Place bread rounds in a single layer on a wire rack; bake until golden brown, about 5 minutes. Arrange in a basket.
Turn tomato sauce into a 9-inch round, square, or similar size ovenproof pan; top with goat cheese discs. Bake until bubbly, about 10 minutes. Turn on broiler; cook until goat cheese lightly browns, 1 to 2 minutes longer. Serve.
