*Oven temperatures can vary greatly which is why a range of times is given. Also, time will be dependent on how much is put into the oven at one time. It is best to use a quick read thermometer to get accurate temperature readings. All cooked foods should be reheated to a temperature of 145°. If you have 2 ovens, you can use one at a lower temperature to reheat the vegetables.
*Matzo Balls should be boiled in a covered pot with water or Chicken Soup for 15 minutes, but cooking in the Chicken Soup will reduce the amount of broth.
