In a medium bowl, whisk together ½ cup of mayonnaise, ½ cup of sour cream, 2 tablespoons of red or white wine vinegar, 1 tablespoon of Italian seasoning, and 2 tablespoons of olive oil. Add 1 clove of minced garlic, a pinch of salt, a dash of pepper, and 1 teaspoon of sugar. Mix everything until blended and smooth. Cover and chill for at least 1 hour.

Once the dressing has chilled, thinly slice 2 cucumbers and ½ a red onion into uniform pieces, about 1/8 to 1/4 inch thick. Place the sliced vegetables in a large mixing bowl and set them aside.

Pour the chilled dressing over the bowl of sliced cucumbers and red onion. Using a spatula, gently fold the dressing into the vegetables until evenly coated.

Serve the Creamy Italian Cucumber Salad immediately or cover tightly and chill for another hour before serving.
