You can use whatever spring vegetables you have on hand - leeks, spring onions, beets, parsnips, carrots, fennel etc. Like I mentioned above, adding a poached egg on this dish really adds another layer of love. Risotto preference is often personal. If you like your risotto less firm, use more broth, and for firmer risotto use less broth. To reheat add a splash of broth or water and stir over low heat.
