Although you were referring to novels, considering your specific love of books that talk about food and eating, a few in particular come to mind. One is
Under the Tuscan Sun, which details incredible sounding meals in the Italian countryside (as well as the renovation of an old and beautiful home). The movie with the same title had little to do with the book - FYI.
Another writer that made me salivate was Ruth Reichl, who wrote some great memoirs of her life as a chef and food writer including
Comfort Me with Apples,
Tender at the Bone and
Garlic and Sapphires.
All of these are memoirs/non-fiction, but beautifully written and as transporting as a novel, so worth considering
Hope this helps!
