Combine tomato, basil and red onion in a small mixing bowl; stir well. Season with freshly ground black pepper. Set aside.
Toast bread slices on a cast iron tawa till they cook all the way through. Vigorously rub roasted or raw garlic slices on each toast. Heap on the tomato mixture and serve.
To bake, preheat oven to 200 C. Arrange bread on a baking tray. Place in oven, and bake until well toasted, approximately 5 minutes.
Remove bread from oven, and transfer to a large serving platter. Let bread cool 3 to 5 minutes. Rub garlic into the top of each slice of toast; the toast should glisten with the garlic. Spoon the tomato mixture generously onto each slice, and serve.
Try spreading roasted garlic onto the toasted baguette slices for more garlic flavour.
