Preheat oven to 180 degrees Celsius.

Grease a 23cm flan dish.

Melt butter in a frying pan over low heat.

Add sliced mushrooms and cook for 2-3 minutes.

Add chopped red capsicum and cook for 1 minute.

Stir in sliced or diced ham and frozen peas.

Remove the pan from heat and let the mixture cool slightly.

In a small bowl, whisk together eggs, cream (or milk), salt, and pepper.

Add cooked and chopped spaghetti, chopped fresh parsley, and the mushroom mixture to the bowl.

Stir to combine all ingredients thoroughly.

Pour the mixture into the prepared flan dish.

Sprinkle freshly grated parmesan cheese (or pre-bought parmesan) evenly over the top.

Bake in the preheated oven for 25-30 minutes, or until golden brown and set.
