Split dates in half lengthwise and open the date. Add 1t of blue cheese to the middle of each date and close the date around the cheese.
Lay a piece of bacon out on a flat surface and place the date at one end of the bacon. Roll up the date, wrapping the bacon around the date. Periodically stretch the bacon slightly to ensure a tight wrap around the date.Repeat for each date.
Place dates in the air fryer basket, seam-side down, cooking in batches, if necessary. Set the fryer to 10 minutes.
When done, remove the basket. The bacon should be brown and crispy and the cheese should be melting and slightly oozing from each date.
Plate the dates with Hoisin sauce or sauce of choice. Garnish with chives and enjoy.
