Combine TABASCO® Green Sauce, garlic, oregano and salt in medium bowl. Gradually whisk in olive oil. Add chicken. Marinate 30 minutes.
Preheat grill to medium-high heat. Grill chicken until just cooked through, turning occasionally, about 7 to 9 minutes. When chicken is cool enough to handle, cut into 1-inch pieces.
Toss tomatoes, cucumber, olives, red onion and mint in large bowl. Add grilled chicken. Combine olive oil, red wine vinegar and oregano in small bowl. Drizzle over salad; toss well. Season with salt and pepper.
