Hmm, dinner? Lets see...
I am much like Imaginos in the fact that I love to cook, just not for myself. That truely sucks. So I go to my friends house and I cook for them when I tire of not being able to cook.
My specialty is Italian...let me explain that I made for Christmas dinner two hams and a larger than life kettle of sauce for the pasta, so...
Last meal I prepared was Fried Spegetti. Heat up a frying pan, add real butter to suite your tastes (I like alot of it), add leftover pasta (from the xmas dinner, which is alrdy lightly coated with the sauce), fry the pasta in the butter as you add the leftover sauce (which btw was prepared with tons of hot or mild sausage, tiny meatballs-peices of beef, pork, and pepperoni-1/4'ed green peppers, and cooked for an entire day), lightly brown the pasta, then add the rest of the sauce to cover it fully. Sprinkle on parma and Romanio cheese (I spell for crap), and eat it! You can also bake it in the oven after it is fried, with tons of mazzarela (sp)and romanio and parma cheese coating it.
I generally drink either green tea or diet pepsi and I call it a day.

IMHO left over pasta can be prepaired in many diferent ways, and in my kitchen it usually is.
