In a medium bowl, combine the cucumbers, tomatoes, parsley, and red onion.
In a small bowl, stir together 1-1/2 tablespoons lemon juice, oil, paprika, and salt and pepper to taste (I add 1/4 teaspoon salt and 1/8 teaspoon pepper). Whisk with a fork. Drizzle dressing over vegetables and stir to coat.

Notes
Storage: It's best to enjoy this salad fresh, as the tomatoes don't last long. If you have leftovers, store them in the fridge for up to 1-2 days, but they may lose some of their crunch.
