This is a recipe I have been using for a long time and I have experimented with different oils.  Many kinds work fine: grapeseed oil, canola oil, regular vegetable oil, sunflower oil... All I suggest is using a good quality one.  You don't have to but your taste buds will thank you!  I took this dressing with a salad last night to a church function and it disappeared at an alarming rate.  So here is the recipe for you to try.  Feel free to adjust the sugar ratio to your taste and/or use honey instead.  This is great on a variety of salads and I love dipping plain old cucumbers in it for an afternoon snack.  Mmmm. Enjoy!
 
  
 
Deliciously Sweet Red Wine Vinaigrette
3/4 cup Safflower oil (or your favorite clear vegetable oil)
1/4 cup extra virgin olive oil
1/2 cup red wine vinegar
3/4 cup sugar
2 cloves garlic, pressed
1/2 tsp kosher salt
1/2 tsp smoked paprika
In a salad dressing shaker or large mason jar combine oil, sugar, vinegar, garlic, salt and paprika.  Seal the lid and shake well until completely combined.  Store extra in the refrigerator.
