Cook the pasta in salted water until al dente and drain.
Heat both oils in a wok, add the chili peppers and cook over a medium heat for 1 minute while stirring. Then add the cashew nuts and roast for 1 minute while stirring until golden brown. Put the vegetables in the wok and cook over a medium heat for 3 minutes so that they still have bite. Then add the pasta and sauces and stir well until everything is completely heated.
