Make the dressing. In a small bowl, whisk together the garlic, lemon juice, olive oil, and a good pinch of salt and pepper. Whisk well to combine. Add the jalapeno or ancho pepper, if using, and give it another whisk.
Dress and serve. Arrange the sliced tomatoes on a large plate. Drizzle with as much of the dressing as you like. Top with the dukkah and mint and serve.
