Ingredients – what you need
To make this recipe you'll need the following ziti pasta (or another short pasta shape)canned plum tomatoes, mascarpone, parmesan cheese, garlic, fresh basil, dried oregano, red bell peppers, red onion and spinach.
See the photo below that shows you all the ingredients you need!

Heat the olive oil in a large frying pan or skillet. Once hot add the sliced bell peppers and sliced red onion. Fry the vegetables, stirring often until they start to soften for around 5 minutes.
Add the minced garlic and oregano to the vegetables and cook for a further 5 minutes (photos 1 & 2).

Add the canned tomatoes then rinse out any leftover tomato from the cans with water and add that to the sauce. Stir until everything is combined and simmer for 10 minutes (photos 3 & 4).
Turn off the heat and stir in the mascarpone, season well with salt and pepper (photos 5 & 6).
While the sauce is simmering add the pasta to the boiling water and cook for around 7 minutes so it's slightly undercooked.

Drain the pasta and add to the sauce along with the spinach and basil, stir to combine (photos 7-9).
Transfer the pasta to a large baking dish and top with mozzarella and parmesan. Bake for 20-25 minutes until the cheese is bubbling and golden on top (photos 10-12).
