Mediterranean Pepper Salad

My new favorite recipe!  
This isn't the best picture but don't let this fool you because this salad is amazing!!

1/4 cup red wine vinegar
1/4 cup cold water
1 teaspoon kosher salt
2 teaspoons sugar
1/2 a red onion, cut into a 1/2-inch dice (use less if your onion is huge)
3 bell peppers, your choice of colors (I used one red, orange and yellow)
1 c. grape tomatoes
1 kirby cucumber,
1/4-pound firm feta cheese
1/4 to 1/2 cup pitted kalmata olives
1/4 cup olive oil
Salt and pepper to taste

Swish together the red wine vinegar, water, kosher salt and sugar in a small bowl until the salt and sugar are dissolved. Add the red onion and set it aside.

Core and seed your bell peppers and chop them into 1/2-inch pieces. Chop the cucumber and feta into similarly-sized chunks. Put your peppers, cucumber, feta and olives in a large bowl.

By now, your onions will have lightly pickled, both sweetening and softening their blow. Drain them and add them to the other vegetables in the large bowl, but reserve the vinegar mixture. Pour a quarter cup of the vinegar mixture over the salad, then drizzle with olive oil. Season generously with salt and freshly ground black pepper, or to taste. Toss evenly and serve at once, or let the flavors muddle together in the fridge for a few hours.
