Preheat the oven to 375 degrees. Line a baking sheet with foil and lay out six strips (or more) of bacon. Bake for 20 minutes (more or less depending on thickness of bacon).
While bacon is cooking, bring water to a boil in a large sauce pan and chop green onions, wash tomatoes and spinach, and shred Parmesan cheese.
Remove bacon from oven, let cool for 5 minutes on a plate lined with a paper towel, then chop into bite sized pieces.
Add orzo and a pinch of salt to the boiling water. Cook for 9 minutes. Strain and set aside cooked orzo in a serving bowl.
