Step 1 Start by greasing a casserole dish then set aside. Slice zucchini in half lengthwise. Using a melon baller or metal teaspoon, hollow out the center of zucchini.

Step 2 Next heat the teaspoon of olive oil in a large skillet over medium heat. Add the onion and the peppers and cook for 2-3 minutes. Then add the quinoa, corn, and beans along with the tomatoes, chilli powder and cumin.Add salt to taste. Stir everything together and continue to cook for about 5 minutes then remove the skillet from the heat and set aside.

Step 3 Preheat the oven to 400°F or 200°C. Spoon the filling inside of each zucchini until they are all full. Sprinkle each one with cheese then arrange them in the dish and cover with foil. Bake in the oven for 25 minutes then remove the foil.
