1. Heat the olive oil in a skillet over medium heat. Add the onion, thyme and a little salt and pepper. Cook until the onions begin to get soft. Turn the heat up a little and cook until the onions turn golden brown. Adjust the salt and pepper to taste.
2. Toast the bread on both sides in a toaster oven, under the broiler or on the grill.
3. While the toasted slices are still warm, rub them with garlic and drizzle them with extra virgin olive oil on one side.
4. Place a dollop of the caramelized onions on each slice of bruschetta and top with half an olive.
