1. Preheat oven to 425ºF convection or 450ºF traditional oven.
2. Place quinoa in medium saucepan with 1 cup water. Bring to a boil, reduce heat to low, cover, and cook 15-20 minutes until tender.
3. Cut zucchini in half lengthwise. Using a paring knife, cut a V shape into each half and remove the center, creating a channel for the stuffing. Chop the zucchini that has been removed and save it for use in the stuffing.
4. In the meantime, place the olive oil in a large sauté pan. Add pancetta, onion, garlic, and chopped zucchini. Sauté until pancetta is browned. Remove pan from heat and add tomatoes. Add cooked quinoa and mix well.
5. Stuff each zucchini half with 1/2 cup quinoa mixture and place on parchment-lined baking sheet.
6. Bake 20-25 minutes until zucchini are fork tender. Stuffing will be nicely browned.
