Bring a large pot of salted water to the boil then add the pasta and cook as per packet instructions until al dente. Drain and set aside.
Whilst pasta is cooking grill the sausages under a medium grill, or use a George Forman grill, once cooked lay aside to cool. Then cut the sausages in half and each half into 4 quarters.
Heat the olive oil in a large saucepan. Add the onion and garlic and sauté until softened, about 3 to 4 minutes. Then add the pepper and sauté stirring for a further 2 to 3 minutes until soft.
Stir in the baked beans, chopped tomatoes, mustard, and bring to a simmer. Add the drained pasta and sausage pieces then season with some salt and black pepper. Turn the contents into an oven proof dish. Top with the grated cheddar cheese.
Bake for about 15-20 minutes until the cheese has melted on top and is golden coloured.
Serve immediately with a mixed leaf green salad.
Notes
* I prefer to use chicken sausages, but you can use any low-fat sausages.**This dish is suitable to freeze.
