Spinach Salad with Warm Bacon Dressing

Who am I?  I am reading my Food Network Magazine for March 2014; it is devoted to bacon.  What is the first recipe I want to try???  Spinach salad with warm bacon dressing!

5 slices of bacon, roughly chopped
1/4 C. white wine vinegar
1 tsp. sugar or honey
1 tsp. Dijon mustard
Kosher salt and freshly ground pepper
2 tbsp. extra virgin olive oil
1 pound of spinach (not baby spinach), tough stems removed
2 c. seedless red grapes, halved
4oz. blue cheese, crumbled (about 3/4 C.)  I wonder how goat cheese would taste here??
Croutons for topping

Cook the bacon in a medium skillet over medium heat, stirring occasionally, until crisp, 9 to 11 minutes.  Remove to paper towels; reserve the drippings in the skillet.

Whisk the vinegar, sugar, mustard and 1/4 tsp. each salt and pepper into the drippings.  Slowly whisk in the olive oil until emulsified.

Place the spinach in a large bowl and pour the warm dressing on top; ad the brapes, blue cheese and the reserved bacon and toss.  Season with salt and pepper.  Top with croutons.
