Aioli, which is basically garlic mayonnaise, is even tastier when you add green olives, but you can also use black olives, a few basil leaves and some capers. I guarantee it will be a great flavor contribution to any sandwich. Before you get started, i have a trick to share: if you cook raw garlic in a little water or roast it in a few drops of olive oil, its flavor will be gentler and you won.
