Preheat the oven to 375°F. Place the chicken in a cast iron skillet or roasting pan, and season with the garlic and herb seasoning. Roast the chicken for 25 minutes per pound, until a meat thermometer reads 165°F in the thickest part of the breast, approximately 1 hour and 40 minutes for a 4-pound chicken.
In a large salad bowl, toss the baby greens with the endive, kale, radicchio, and red onion. Add the sliced pear, tomato, pecan halves, and dried cranberries.
In a small mason jar, combine the olive oil, fig balsamic vinegar, salt, and pepper. Seal the jar and shake vigorously to combine the dressing. Toss the salad with the dressing and serve with the chicken.
