"Create a classic panzanella recipe adapted for a household of 3, using imperial units, beginner-friendly, quick and easy (15-30 minutes), minimal processing, moderate budget, and low-inflammation friendly. Exclude gluten, dairy, nuts, shellfish, and corn. Since traditional panzanella uses bread, make it gluten-free with a suitable gluten-free bread or alternative, and keep it fresh, simple, and flavorful. Include common vegetables like tomatoes, cucumber, red onion, basil, olive oil, and vinegar, with optional protein if appropriate."
