Cook the pasta according to the packet's instructions. Drain well. In the meantime, preheat the oven to 200 degrees Celsius/ 400 degrees Fahrenheit.
Prepare vegetables: Clean and chop the bell peppers, green onions (reserve 1 tablespoon greens for sprinkling on the pasta bake at the end), carrot, cherry tomatoes into small pieces. Drain the corn. Mix the vegetables, ham or bacon, and pasta in the pot you used to cook the pasta.
Make the sauce: Mix the eggs, milk, mustard, grated garlic, and dried herbs. Adjust the taste with salt, pepper, and nutmeg. Pour this mixture over the noodles and vegetables and stir. Mix in half of the cheese. Transfer to a lightly buttered baking dish.
Bake: Sprinkle the remaining cheese on top and bake for about 30 minutes until the cheese is golden.
Rest: Remove from the oven, let stand for 5 minutes, sprinkle with the remaining green onions and serve with a green salad.
Notes
Gouda or Cheddar. Or any other cheese you like to use for making pasta bakes.
