In a bowl mix together vinegar, olive oil, honey and thyme. Mix and then pour mixture into a gallon size freezer bags. Put chicken thighs into bag. Zip closed and move around so chicken is coated. Then lay flat and put in fridge for at least 2 hours to marinate.
Preheat oven to 400 degrees. Prepare 1-2 large sheet pans with foil lined on top for easier clean up. Spray each with non stick spray or use non stick foil.
Remove chicken from marinade and place on sheet pan. Sprinkle with salt and pepper. Cook for 50-60 minutes or until chicken is cooked through to 165 F and roasted to a golden brown on top.
