In a large bowl, toss together the spinach, strawberries, almonds, and feta cheese. Set aside.
Next, preheat oven to 375 degrees.
In a medium size bowl, combine bacon, brown sugar, and cinnamon until bacon is thoroughly coated.
Arrange in a single layer on a cooking sheet and cook for 8-10 minutes until dark brown, flipping once about halfway through.
Allow to cool.
In a large mason jar (with a lid), combine oil, vinegar, salt, and cracked pepper.
Crumble the now cooled bacon and add to vinaigrette jar.
Close lid and shake until thoroughly blended.
Lastly, pour vinaigrette mixture over salad mixture and toss until well coated.
Enjoy!
