Slice the pork belly into 1/2-inch cubes. Combine the rubs, and toss on the cubes.

Heat your smoker to 225F degrees. Place a mesh mat on the grill grates. Add the seasoned pork belly cubes in a single layer.

Smoke for 2 hours and 15 minutes. The meat should start to caramelize on the edges.

Place in an aluminum pan. Add the sauce, butter and honey and toss.

Cover with foil and return to the smoker for 1 hour.

Remove the foil and continue to smoke for 30 minutes.
