Cook the Bacon: Begin by heating a skillet over medium heat. Add the bacon strips and cook for 6-8 minutes, turning occasionally until crispy. Transfer to a plate lined with paper towels to drain.

Prepare the Tortellini: In a large pot, bring salted water to a boil. Add tortellini and cook for 3-5 minutes until al dente. Drain and rinse under cold water. Set aside to cool.

Make the Dressing: In a mixing bowl, combine mayonnaise, red wine vinegar, a pinch of salt, oregano, Italian seasoning, garlic powder, and red pepper flakes. Whisk until smooth.

Combine Ingredients: To the bowl with dressing, add cooled tortellini, sliced pepperoncini, grated Parmesan, diced red onion, halved tomatoes, and crispy bacon. Toss until well combined.

Chill the Salad: Cover and refrigerate for at least 1-2 hours to allow flavors to meld.

Serve and Enjoy: Give the salad a gentle stir before serving. Serve chilled or at room temperature.
