ITALIAN BROCCOLI & SALMON BAKE

Steps:

• Preheat the oven to 375F and get out an ovenproof dish (measuring 8 by 12in, and about 2in deep).
• Meanwhile, put a large pan of water on to boil for the pasta. When it is boiling rapidly, tip in the pasta with a generous sprinkling of salt.
• Give it a stir, return to the boil and cook for 6 minutes. Add the broccoli, then return the water to the boil and cook for 4 minutes more, until the broccoli is on the firm side of just tender. Drain well.
• While the pasta is cooking, put the butter, flour and milk in a large pan and heat, whisking or stirring continuously, until it thickens to make a smooth sauce.
• Remove from the heat and stir in the mascarpone, sun-dried tomatoes, capers (if using), anchovies (if using) and basil, then add the pasta and broccoli and season well.
• Halve the salmon fillets widthways (you will see that there is an obvious divide on each fillet) then place the pieces in a single layer on the base of the ovenproof dish.
• Spoon the broccoli mixture on top, then scatter with the grated cheddar. (You can chill this for up to 4 hours if you want to get ahead.)
• Bake for 30 minutes until the mixture is just starting to bubble round the edges and the mixture is pale golden - don't let it go too dark or the fish will overcook.
