Homemade Mayonnaise (or Ranch Dressing)

Ingredients:
1 big container (17 oz) of Greek yogurt (I used Fage)
3 tbsp white vinegar
5 packets of Stevia (if you use Truvia, use about 3)
2 tsp Dijon mustard
1 tsp salt

Instructions:
Mix all ingredients. You can also cut all ingredients in half and make less. 
You can also add some herbs to turn the mayo into a dip. My husband loves Ranch dressing and he says this mayo tastes almost like Ranch dressing :-)
