It really pays off to check my recipe folder every now and then. I just found this little gem, simple dish that all 3 of us liked a lot. Not perhaps particularly light, but very tasty. Conchiglie were cooking as long as they were to cook according to packet instructions, while I finely chopped a shallot, fried it on olive oil, added some roughly chopped nice ham, a handful of frozen peas and then a good, generous splash of double cream. A tsp of English mustard. A generous handful of grated mature cheddar. Seasoned. A few broccoli florets go in with the pasta for the last 3 minutes of cooking time, then onto the pan with the rest of of stuff, well coasted in creamy sauce. A sprinkling of parmesan is never a bad idea. Simple and delicious.
