Cook the pasta as directed on the package.
Apply a thin layer of low-fat cooking spray to a pan. Once added, sauté the mince until browned.
Add paprika, garlic, mustard powder, and a small amount of salt. Cook on medium heat for two minutes.
Turn the oven on to 200°C (180°C for fans) or Gas 6.
Add the pickles, onion, tomatoes, beef stock, and tomato puree. Simmer, uncovered, until the mixture thickens and most of the liquid has reduced 10 to 15 minutes.
After adding the cooked pasta, stir everything together and pour it into a baking dish.
Evenly scatter the grated cheese on top, then bake for 20 to 25 minutes, or until the cheese turns golden brown.
