Dice the onions, ham and sundried tomatoes and cut the spring onions into slices.
Bring about 2.5 liters of water to the boil in a saucepan, add salt and cook the pasta in it for about 6 - 8 minutes.
Meanwhile, fry the onions in a little olive oil over medium heat until they turn slightly translucent, then add the sun-dried tomatoes and the diced garlic, or press the garlic through the press. After approx. 3 minutes, add the spring onions and fry for another 1 - 2 minutes. Then pour in the cream, stir in the processed cheese and season to taste. Let it simmer on a low heat.
When the pasta is soft enough, add about 4 teaspoons of pasta water to the sauce, drain the rest and drizzle the pasta with a little olive oil and add to the sauce. Add cocktail tomatoes, prawns and parmesan and cook for another 2 - 3 minutes.
The quantities can of course be adjusted as required. You may have to season a little more or less, as I usually season with a sense of proportion and the amounts of spice are therefore estimated.
