If I am a diabetic and avoid sugar, what can I sub for the honey in this recipe?

Hi Vicky! The other substitutions I would suggest for the honey in this recipe are also sweet—say, maple or agave syrup. Because the ingredient list is so small and relies on the sweetness for balance, your best bet might be pivoting to another miso dressing with a different formula.
