Turn broiler on high.
Drizzle 1 tablespoon of your sweetener over the two grapefruit halves and place on a sheet pan. Broil until nice and charred, approximately 10 minutes.
While the grapefruit is broiling, whisk together the remaining sweetener and Vanilla Cashewgurt®.
Remove broiled grapefruit and drizzle with Cashewgurt® mixture, garnish with hemp seeds and enjoy.
