Preheat the smoker to 300 degrees F (150 degrees C).
Cook the pasta as per the packet’s instructions. Drain and put aside until needed.
Place in the foil pan the feta in the center then surround it with the cherry tomatoes and garlic cloves. Drizzle with the olive oil and sprinkle with the BBQ seasoning, then the finely diced herbs.
Place in the preheated smoker and cook for 30 minutes or until the tomatoes are soft and the cheese is starting to brown on the edges.
Remove the foil tray from the smoker and stir to squash the tomatoes and break up the feta. Add the cooked pasta and spinach then fold into the feta mixture. Cover with foil and let rest for 5 minutes before serving.
