In a large pot of boiling water, add 1 tablespoon of oil. Cook the tortellini according to package instructions until al dente. Drain and transfer to a large bowl.
Season the cooked tortellini with salt and pepper. Add balsamic vinegar and 1/4 cup of olive oil, then mix well to combine. Set aside.
Marinate the mozzarella: In a small bowl, combine the mozzarella balls, Italian seasoning, red pepper flakes, and the remaining 1/4 cup of olive oil. Mix well and set aside.
Assemble the skewers by layering one piece each of mozzarella, salami, roasted red pepper, tortellini, basil, artichoke heart, and green olive. Enjoy the burst of flavors!
