In a blender, combine tomatoes, bell peppers, cucumber, and onion, and in small batches until smooth.
Add garlic, olive oil, vinegar, basil, and parsley to the blender. Combine.
Put the finished mixer in a large bowl or pitcher. Cover and chill for at least 2 hours or overnight. If you want to drink this right away, add ice cubes to the blender and combine.
Stir well and taste for seasoning before serving. Serve in bowls or large mugs. You can top your soup with croutons, parsley, diced veggies, or sour cream.
