Risotto is pretty easy to make on a whim if you have the basic ingredients. You want a short grained rice (Arborio is best), chicken or vegetable broth, your choice of herbs and seasonings, some Parmesan cheese and BACON!!
You can also add cooked chicken, shrimp, a mixture of spring veggies, mushrooms or all sorts of things. Usually the add ins are cooked and then added once the risotto is creamy. A drizzle of truffle oil on top is always amazing. :-)
