Start by cooking the bacon in a skillet until it’s crispy. Once cooked, drain the grease and place the bacon on a paper towel to soak up any excess oil. Chop the bacon into small pieces and set aside for later use.

Bring a pot of water to a boil on the stove and cook the cheese tortellini according to the package directions. Once done, drain the tortellini and rinse it with cold water to stop the cooking process. Set the tortellini aside while you prepare the other ingredients.

In a large bowl, combine the following ingredients: mayonnaise, red wine vinegar, a pinch of salt, oregano, Italian seasoning, garlic powder, and red pepper flakes. Stir everything together until fully mixed, creating a well-blended dressing.

Add the cooked and cooled cheese tortellini, pepperoncini peppers, 1/3 cup Parmesan cheese, chopped red onion, sliced tomatoes, and the chopped bacon to the bowl with the dressing. Gently toss everything together until all components are evenly coated with the dressing.

Cover the bowl and refrigerate the tortellini salad for at least an hour. This will allow the flavors to meld and the salad to cool. When ready to serve, give it a good stir, plate it up, and enjoy your delicious bacon tortellini salad!
