Step 1: Cook the Tortellini
Bring a large pot of salted water to a boil. Add the tortellini and cook according to package directions, usually 3–5 minutes for refrigerated types. Once tender, drain and immediately rinse under cold water to stop the cooking process. Set aside to cool.

Step 2: Chop the Veggies
While the tortellini is cooling, prep your vegetables. Halve the cherry tomatoes, dice the cucumber and bell pepper, thinly slice the red onion, and halve the olives. If you’re using mozzarella balls, cut them in half (or cube the mozzarella if you’re using a block).

Step 3: Make the Dressing
In a small bowl or jar, combine olive oil, balsamic vinegar, Italian seasoning, salt, and pepper. Whisk or shake until well combined. Taste and adjust seasoning if needed.

Step 4: Combine Everything
In a large mixing bowl, toss the cooled tortellini, vegetables, olives, and mozzarella together. Pour the dressing over the top and gently toss to ensure everything is evenly coated.

Step 5: Garnish and Chill
Top with fresh basil if you like, and either serve immediately or let it chill in the fridge for 30–60 minutes. This allows all the flavors to blend beautifully.
