If apple-smoked bacon is not available, your favorite kind will work just fine.
How to Make It
Step 1
Cook bacon in a large skillet until crisp; remove bacon, and drain on paper towels, reserving 1/4 cup drippings in skillet. Crumble bacon, and set aside.
Step 2
Combine vinegar, mustard, and, if desired, 1/2 cup crumbled blue cheese, stirring until mixture is smooth.
Step 3
Add vinegar mixture and onion to hot bacon drippings in skillet over medium heat, stirring to coat. Add bacon, parsley, salt, and pepper. Add spinach and endive; toss in skillet just until combined. Serve immediately. Top with additional crumbled blue cheese, if desired.
Step 4
*1/2 (10-ounce) package fresh baby spinach may be substituted.
