In a large bowl, combine peas, cucumber, and tomatoes. Sprinkle with salt and pepper. Refrigerate for 20 minutes.
In a small bowl, whisk together oil, vinegars, and garlic. Add sugar, and whisk to combine. Pour dressing over veggies. Sprinkle with dill and red pepper. Serve immediately, or cover and serve within the hour. The cucumbers will start to pickle if you wait too long.
