Prep the vegetables: Chop tomatoes, cucumber, bell pepper, and red onion into even pieces so they blend easily.
Pulse in batches: Add about one-third of each vegetable to a food processor. Pulse until you get a small, even chop—think salsa-like, not purée.
Transfer to a large bowl. Repeat with remaining veggies.
Add flavor base: Stir in the garlic, tomato juice, olive oil, and red wine vinegar. Season with salt and pepper.
Adjust texture: If you prefer smoother soup, blend a portion longer or use an immersion blender directly in the bowl.
For chunkier soup, keep the pulses short.
Chill thoroughly: Cover and refrigerate for at least 2 hours, preferably 4. This lets the flavors meld and the soup thicken slightly.
Taste and finish: Before serving, taste and adjust salt, pepper, or vinegar. If it’s too thick, splash in more tomato juice.
Garnish and serve: Ladle into bowls and top with a drizzle of olive oil, fresh herbs, and crunchy croutons or diced veggies.
