To make Mayonnaise Nouvelle:
First, make the yogurt cheese by draining the yogurt as follows. Line a colander with cheesecloth and place in a bowl. Spoon the yogurt into the colander. Refrigerate and let drain for at least 1 hour. Discard the liquid in the bowl(or use for another recipe).
In a food processor, combine the yogurt cheese, tofu, and garlic. Process until the mixture is pureed, about 3 minutes. Add the remaining ingredients. Process again to combine, about 3 minutes. Adjust the seasoning with additional salt or pepper, to taste.
This dressing will keep for up to 2 weeks in an airtight container in the refrigerator.
