Brown the turkey bacon: In a large pot over medium heat, add 1 lb. ground turkey bacon. Cook until browned, stirring occasionally for about 5-7 minutes.
Add the onion: Incorporate 1 medium onion, chopped, and sauté until the onion is softened and translucent, approximately 3-4 minutes.
Stir in garlic and herbs: Add 3 cloves garlic, minced, 1 tsp dried basil, 1 tsp dried oregano, 1 tsp dried parsley, ½ tsp dried thyme, and 2 pinches red pepper flakes; stir and cook for 1 minute until fragrant.
Incorporate tomato paste and broth: Whisk together 1 ½ tbsp tomato paste with 2 cups low sodium beef broth and add this mixture to the pot along with 4 cups veggie or low sodium chicken broth and 1 can fire-roasted tomatoes (14.5 oz). Bring this to a low boil.
Add tortellini: Once boiling, gently stir in 10 oz refrigerated cheese tortellini and reduce the heat to a simmer. Cook for 10-15 minutes or until the tortellini is tender and cooked through.
Mix in the greens: Stir in 3 cups arugula or spinach until wilted, season with salt and pepper to taste, and top with grated Parmesan cheese for serving.
