Grapefruit Watermelon with Rooibos Tea

Peel the grapefruit, including the membrane, using a serrated knife. Cut away the grapefruit segments from the membrane over a bowl to reserve the juices. Heat the juices with the rooibos tea and honey over low heat until warm. Let the tea bag sit for 10 minutes then remove and let the tea cool. Gently toss the grapefruit and watermelon with the tea mixture and chill until ready to serve.
