Preheat the oven to 375°F (190°C). Arrange the bell pepper halves in a lightly greased baking dish. In a large bowl, combine the cooked quinoa, chickpeas, cherry tomatoes, red onion, feta cheese, parsley, olive oil, and lemon juice. Add The Holly Tree Organic Italian Seasoning, The Holly Tree Organic Black Pepper Powder, and Salt. Mix well until evenly combined. Spoon the filling generously into each bell pepper half, gently pressing it down. Cover the baking dish loosely with foil and bake for 25 minutes. Remove the foil and bake for another 10–15 minutes, until the peppers are tender and the filling is lightly golden. Garnish with a little extra parsley and a light sprinkle of The Holly Tree Organic Italian Seasoning before serving.
