How to Make It
In a large bowl, combine the grated tomatoes, garlic, olive oil and cilantro. Add the chicken and coat thoroughly with the marinade. Cover and refrigerate overnight.
Light a grill. Thread the chicken onto 8 metal skewers, leaving a small space between each piece. Brush the chicken with vegetable oil and season with salt and pepper. Grill over moderate heat, turning occasionally, until lightly charred and just cooked through, about 15 minutes.
