I build left overs in to my cooking so if I'm making a baked potato I will actually make 3. One I eat and the others are made in to gnocchi the follow day.
To make gnocchi just mix equal quantities of potato (mash it up without the skin) and flour. roll into balls and then squash a bit with a fork. Add them to boiling water and when they float they are ready.
Things on toast, beans, beans and cheese, cheese, egg, bacon and cheese...
@Flippityflops I do veg and fish sometimes too, in a steamer you can just wrap it in foil, add any herbs and seasonings to the foil parcel.
It works with chicken as well.
There is a really old fashioned method I was taught at school were you put potatoes on to boil, then put a metal plate on top, put the fish on the plate and put the lid over the fish and it will steam without and water.
Really easy pasta sauce. Cook the pasta in water and then switch off but do not drain. get a frying pan and dollop some ream cheese in to it, as it heats it will melt, put a couple of tablespoons of the pasta water in to it. Add salt and pepper and herbs if you like.
Drain the pasta and then put in to the frying pan to coat the pasta.
If you like you can fry mushrooms, or onions, or garlic, or bacon before adding the cream cheese.
I'm another fan of tray bakes. Chicken or salmon are my favourites, slice an onion, some mushrooms, peppers, and I might put a slice of lemon on top of the chicken. Season, spray with that one spray oil and bake for 20-30 mins.
I have two slow cookers in the small one I put pork (usually ribs) a jar / packet of passatta a tin of cannellini beans (drained) and chopped chorizo, salt and pepper switch on and leave. Serve with crusty bread.
