Begin by heating the olive oil in a skillet over medium heat.  Add in the onion, celery and carrots. Cook for 2 minutes before adding in the spices (reserving about 1/2 of the cumin, salt & pepper). Cook for another 2 - 3 minutes until softened but still holding a bite.  Remove from heat and let cool.Now, add the remaining spices to the ground turkey with the vegetable mix.  Mix really well and form into a loaf.Place the loaf on a big piece of aluminum foil and place in a 250 degree smoker. Total cooking time will be approximately 3 hours. In the last half hour of cooking, remove the foil and place the meatloaf directly on the grates. Next, liberally apply the glaze a couple of times before removing from the smoker.Let rest for 5 minutes.  Cut in slices.Serve and enjoy!
