Combine water, honey, nutmeg, cinnamon, apple, and orange zest in medium pot; bring to a boil, reduce heat, and simmer 2 minutes.
Cover, remove from heat, and let steep 15 minutes. Strain through a fine mesh sieve over the green tea leaves, pressing all the juices from the apple. Let steep for 1 minute. Strain out
the tea, reheat if necessary, and serve. Garnish with apple slices.
