Preheat the Gateway Drum Smoker to 300F.
Meanwhile, lightly season one side with a sweet spice rub like one (I used my own Chicken spice rub that is more sweet than salty)
Place grill rack on the middle prongs (middle level)
Place watermelon on the grill rack with spice rub facing upwards.
Place lid on Gateway Drum Smoker and allow to cook for 5 minutes. The spice rub on the watermelon will sweat.
Flip the watermelon and lightly rub the “cooked side.” Leave the watermelon to cook for an additional 5 minutes with lid on.
Flip watermelon slices and cook for 2 more minutes.
Remove watermelon from smoker and remove rind and slice watermelon into cubes. Allow to cool.
Place the cubed (uncooked) watermelon into a large bowl
Add the grilled watermelon to the large bowl
Add mojito mint and gently toss watermelon to mix
Sprinkle goat cheese crumbles on top. Serve or place into fridge until it is ready to be served.
