Preheat the oven on 375 F.
Place the ground turkey, vegetables, eggs, oatmeal, bread crumbs, seasonings, and 1/4 cup of the barbecue sauce in a large bowl. Mix the ingredients using your hands.
Mold the meatloaf, then brush on some of the remaining barbecue sauce on to the meatloaf.
Cover the meatloaf, and place in the oven for 25 minutes.
Remove from the oven, uncover, and pour the remaining barbecue sauce all over the meatloaf.
Place the meatloaf back into the oven uncovered for 10 to 15 minutes.
Let the meatloaf sit for 5 minutes before cutting into it.
