For seafood with an Italian flair, The Umberto Menghi Seafood Cookbook (David Robinson/Key Porter $14.95) features such recipes as shrimp canapes, tuna with avocado and mustard sauce, pan-fried fillet of sole with pine nuts and warm lobster salad with apple and papaya. Packaged by the producer of Susan Mendelson's hugely successful first cookbook and The Umberto Menghi Cookbook (50,000 sold), this marriage between distinctly B.C. cuisine and Italian flamboyance is sure to increase the broadening reputation of Menghi, owner of five restaurants in Vancouver, one at Whistler Mountain, B.C. and one in San Francisco.
