Start by bringing a large pot of salted water to a rolling boil. Add the tortellini and cook according to package instructions, usually around 7-10 minutes, until al dente. Drain and rinse under cold water to stop the cooking process.

While the tortellini is cooling, slice your chosen deli meats into bite-sized pieces, about ½ inch wide. Also, slice your cheese into similar-sized chunks.

Rinse and prepare your vegetables. Dice the bell peppers, olives, and red onion into small, uniform pieces and set aside in a mixing bowl.

In a large mixing bowl, toss together the cooled tortellini, chopped deli meats, cheese, and prepared vegetables. Ensure a well-distributed mixture.

Mix mayonnaise with Italian seasoning in a separate bowl, then pour over the combined ingredients. Stir gently until everything is coated with dressing.

Transfer your salad to a sealed container or cover the bowl with plastic wrap. Chill in the refrigerator for at least 30 minutes before serving.
