Step 1Mix tomato, vinegar and oil in small bowl. Season with salt and pepper. Let rest 30 minutes at room temperature. Stir in basil; taste and adjust seasonings with salt and pepper.
Step 1Put bread on baking sheet. Mix oil and garlic in small dish; heat in microwave oven 1 minute. Strain through fine sieve, pressing oil from garlic. Discard garlic. Combine garlic oil and goat cheese. Spread mixture over cut side of bread, dividing evenly. (Can be done several hours ahead and kept at room temperature.)
Step 2Bake bread at 375 degrees, uncovered, until very warm, about 5 minutes.
Step 3To serve, use slotted spoon to separate topping from juices and transfer to bread halves, dividing evenly and spreading to edge. Cut each piece crosswise in half or in smaller portions, depending on how you plan to serve it. Serve immediately while still warm.
