In a large saucepan heat the olive oil and add the sausages. Fry gently for 5-7 minutes until the sausages start to brown. Add the spaghetti, red pepper, cherry tomatoes, tinned tomatoes, boiling water, stock cube, basil leaves and oregano. You may have to snap the spaghetti in two to get it all to fit in. Stir and bring to the boil. Reduce the heat and allow the pasta to simmer for approximately 12-15 minutes or until the water has almost all been absorbed.
