Place the frozen tomatoes and frozen red bell peppers in a blender with the cucumber, red onion, and garlic.
Add the olive oil, sherry vinegar, smoked paprika, salt, and black pepper.
Blend on high until the mixture is completely smooth, about two minutes.
Taste and adjust salt or vinegar if needed, then blend again for a few seconds.
Pour the soup into a large bowl or pitcher and chill for at least one hour.
Stir before serving and divide into bowls.
Top each serving with a sprinkle of fresh parsley.
