Toss together the salad ingredients in a bowl and place in a refrigerator to chill.
For the Dressing:
Use a mortar and pestle to mash the garlic with the salt and pepper.
In a small bowl, add the olive oil, vinegar and lemon juice to the crushed garlic. Whisk together thoroughly. You can also use a blender to emulsify the oil and liquids.
Just before serving: Gradually add the dressing, a little at a time, while you toss the salad with a couple of large salad forks.
Add just enough dressing to cover the salad -- more or less to your own taste.
