Prep dressing, if making from scratch.
Bring a large pot of salted water to a boil and cook tortellini according to package directions, removing from the water when it’s just a little shy of al dente. Drain and let cool for about 2 minutes.
While the pasta cooks, prep remaining ingredients: bell pepper, cucumber, cherry tomatoes, mozzarella, salami, and olives. Set aside.
When pasta is drained and has cooled slightly, pour about 1/4 cup dressing over it and toss to combine.
Add remaining ingredients and toss again. Refrigerate until ready to serve, then pour over additional dressing, toss, and eat!
