Heat the oven to 325 degrees.

Core the tomatoes and slice them into 1/2-inch thick slices. Arrange the tomatoes on a baking tray, drizzle them with 3 tablespoons olive oil, sprinkle them with thyme, and season them with salt and pepper.

Bake for about 40 minutes, until they are somewhat dry and wrinkled. Remove from the oven and reserve.

Turn the oven to broil.

Brush the bread slices generously with 3 tablespoons olive oil and arrange them on a baking sheet. Toast them in the oven for 3 to 4 minutes, until light golden brown.

In a large salad bowl, toss the arugula with the black olives, basil, and enough of the vinaigrette to moisten the leaves.

To serve, top each toast with several tomato slices and then about 1 cup of salad and sprinkle with the crumbled goat cheese.
