For the garlic bread, preheat the oven to the highest setting. Finely chop the garlic and mix with the margarine and parmesan in a small bowl. Spread the mixture over the sliced ciabatta, then bake in the oven for 8-10 minutes until golden and bubbling.
For the pasta, cook the linguine according to packet instructions in a large pan of boiling water. Drain, then return to the pan.
Meanwhile, slice the garlic. Heat the oil in a saute pan over a medium heat and add the garlic and prawns. Cook for 1 minute, then pour in the white wine. Allow to simmer until the prawns are completely pink.
Pour the prawn and wine mix over the linguine and add the chopped parsley, then mix well. Serve with the garlic bread and a little grated parmesan.
