Cook bacon until very crisp and remove to drain on paper towels, leaving as much grease behind as possible.
While bacon cooks, wash and combine greens and scallions. Toss with vinegar. Pour hot bacon grease over greens and toss well until wilted.
Crumble bacon on top of greens, add blue cheese and toss to combine. Salt and pepper to taste and toss well.
Serve with hot corn bread.
