Hard Boil Eggs: Place eggs in a small saucepan. Cover with cold water by about two inches. Bring water to a roiling boil, cover pot, and turn off heat. Let sit for 9 minutes, then drain water and rinse eggs under ice cold water until they cool. Let eggs come to room temperature, peel, and chop.
Make Dressing: In a small bowl or jar, whisk together remaining olive oil, red wine vinegar, and mustard. Pour over spinach and let sit while you assemble the remaining ingredients.
Cook Beets and Bacon:
- Preheat oven to 450F
- Toss beets in 1 tablespoon olive oil. Sprinkle with salt and pepper. Roast for 20 minutes, or until beets are cooked through. Remove and let cool slightly.
- In a small saucepan, cook bacon until slightly crispy. Transfer bacon to paper-towel lined plate
Assemble Salad: In a large bowl, combine dressed spinach leaves, beets, bacon, chopped eggs, scallions, and blue cheese. Toss well, and adjust salt and pepper to taste.
