This salad is beautiful, as well as being delicious and a little bit 'different', even though it is very easy to find ingredients and prepare. Kids and adults love it. It is a family favorite.
In a large bowl, toss together the tomatoes, cucumber, jicama, bell pepper, and red onion. Add the lemon juice, olive oil, and parsley, and mix thoroughly to coat. Season with salt and pepper. Serve cold, or at room temperature.
