1 c mayonnaise
1/2 c white wine vinegar
heaping 1/2 c parmesan cheese
1/4 c sugar
1 T olive oil
1 tsp parsley
1/2 tsp basil
1/2 tsp oregano
1/2 tsp salt
scant 1/4 tsp garlic powder
juice of 1 lemon
Mix all ingredients but mayonnaise in a blender until well mixed. Whisk the mayonnaise into the dressing until it achieves the right consistency. If this is a little too tart for your own personal taste, add a little extra sugar.
Sugar restrictions: replace the sugar called for beginning with 3 pkts of stevia, adding a little more at a time if more sweetness is called for to balance the vinegar.
