Tomato Feta Salad

I got this recipe from Ina Garten aka The Barefoot Contessa - good. easy. simple.
Tomato Feta Salad
4 pints grape tomatoes, red or mixed colors
1 1/2 cups small-diced red onion (2 onions)
1/4 cup good white wine vinegar
6 tablespoons good olive oil
1 tablespoon kosher salt
1 teaspoon freshly ground black pepper
1/4 cup chopped fresh basil leaves
1/4 cup chopped fresh parsley leaves
1 1/2 pounds feta cheese

Cut the tomatoes in half and place them in a large bowl. Add the onion, vinegar, olive oil, salt, pepper, basil, and parsley and toss well. Dice the feta in 1/2 to 3/4-inch cubes, crumbling it as little as possible. Gently fold it into the salad and serve at room temperature.
