Cook the rotini pasta according to package instructions. Drain and rinse under cold water to cool.

In a large mixing bowl, combine the cooled pasta, cherry tomatoes, cucumber, red onion, and bell pepper.

In a small bowl, whisk together the olive oil, red wine vinegar, Italian seasoning, minced garlic, salt, and black pepper.

Pour the dressing over the pasta salad and toss to combine. Add crumbled feta cheese on top and serve chilled.
