Basically a recipe of my own creation

• 2 medium tomatoes, or 1/2 pint of cherry tomatoes, chopped into large pieces
• 1/2 large English cucumbers, chopped into medium pieces
• 1 medium red onion, chopped into medium pieces (and roasted in oven, optional)
• 1 sweet red pepper, chopped into medium pieces (and roasted in oven, optional)
• 1 pint-sized container of mini mozzarella balls (or cut a larger piece of fresh mozzarella into small chunks)
• 1/2 stale baguette, sliced into crouton-sized pieces (if not stale/day-old, toss with olive oil and toast in oven until crunchy)
• Optional: 2 green onions, sliced
• Optional: fresh herbs (parsley, basil, etc.), chopped
• Olive oil and vinegar (balsamic and sherry are a good start), to taste
• Salt and pepper, to taste

Mix everything except baguette pieces in a bowl. Allow flavors to marinate for at least 30 mins or so. Add "croutons" right before serving.
