Wash and dry the garden salad mix thoroughly.

Slice the Roma tomatoes into bite-sized pieces and thinly slice the red onion.

Drain and rinse the black olives if they are canned, setting aside in individual bowls.

In a large mixing bowl, add the garden salad mix, followed by the sliced Roma tomatoes, black olives, croutons, sliced pepperoncini, and red onion.

Gently toss the ingredients together using salad tongs for even distribution.

Top with freshly grated Parmesan cheese and season with salt and black pepper to taste.

Toss the salad gently to coat evenly.

Drizzle the Olive Garden dressing over the salad and toss once more to mix.

Transfer the salad into a serving bowl or plates and serve immediately.

Consider adding protein like grilled chicken or chickpeas for customization.
