I am cooking dinner for some friends tonight. One is pregnant and a vegetarian (but she eats fish). The other is on a migraine diet that doesn't allow her to eat cheese and citrus among other things. I have in my mind some kind of pasta dish with shrimps, scallops and squid. I'm thinking more of a garlic, olive oil with fish broth finish, but I'm having trouble making it congeal in my head. Any ideas?
