1Preheat your oven to 200°C (390°F).
Cook the pasta according to the package instructions until al dente, then drain and set aside.
While the pasta is cooking, dice the green and red peppers, and slice the mushrooms.
In a large pan, sauté the peppers and mushrooms until they are soft, about 5 minutes.
Add the sweetcorn and diced tomatoes to the pan and cook for another 3 minutes.
Combine the cooked pasta with the sautéed vegetables in a large mixing bowl.
Grate the cheese and mix half of it into the pasta and vegetable mixture.
Transfer the mixture to a baking dish and sprinkle the remaining cheese on top.
Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly.
Remove from the oven and let it cool for a few minutes before serving.
