Bring a stock pot of water to a boil.
Preheat your oven to 400 degrees Fahrenheit.
Once the water is boiling, add the pasta and cook according to the package directions.
Place the wire baking rack inside the baking sheet.
Place the bacon on the wire baking rack.
Bake the bacon at 400 degrees Fahrenheit for 20-25 minutes until the desired level of crispiness is achieved.
While the pasta and bacon are cooking, use a knife and cutting board to chop the spinach, halve the grape tomatoes, and chop the green onions.
In a small bowl, combine the nonfat plain Greek yogurt, mayonnaise, white wine vinegar, salt, and pepper with a whisk or spoon.
Once the pasta is done cooking, use a colander to strain and rinse with cold water to stop the cooking process.
Add the pasta to a large bowl.
When the bacon is done cooking, allow it to cool and then chop.
To the large bowl with the pasta, add the bacon, spinach, grape tomatoes, and dressing.
Stir well to combine.
Garnish with green onions and more chopped bacon if desired.
