1/3 cup red wine vinegar
2 tsp minced shallot
1/3 cup extra virgin olive oil
1 ½ tsp sugar
1 tbsp fresh oregano, minced
2 tsp Dijon mustard {smooth or grainy} or ¼ tsp dry mustard
1 clove garlic, finely minced or made into paste
Freshly ground black pepper

Add minced shallot to vinegar & let sit for about 5 minutes.  Add remaining ingredients & whisk together until blended.

This is one of my new favorite dressings.  You can use other herbs, or a mixture, if you like.
