Boil your pasta according to the package instructions. Once cooked, drain and rinse with cold water to stop the cooking process. Transfer the pasta to the fridge to cool for about 5 minutes.

In a large bowl, combine the olive oil, red wine vinegar, feta cheese, black pepper, diced red onion, and a splash of red onion pickle juice. Mix well until evenly combined.

Dice the cucumber and cut the cherry tomatoes in half or quarters, depending on your preference. Add the chopped vegetables to the bowl with the dressing.

Add the chilled pasta to the bowl with the dressing and vegetables. Toss everything together until well-coated. Adjust seasoning to taste if needed. Serve immediately or refrigerate for a cold, refreshing salad.
