I tend to eat comparatively late in the evening (around 8pm) so late snacking seems less necessary than once it did. That said, I am incredibly partial to fine cheeses (as is my cat!) and will quite often make late evening forays to the cheese stash. My favourites tend to be blue cheeses and those made from goats' milk, which liven my palate and lead to a warm, fuzzy, slightly dreamy sensation after their consumption.
During the day, I tend to focus on using up odds and ends, usually either on toast or some other warmed flat bread . Usually, this is based on either overcoming slight boredom or experimenting with a new taste sensation, prior to unleashing it on my long-suffering wife.
Cheese tends to be eaten with biscuits, which make the process rather too noisy whilst watching TV as I like to focus on every nuance of the script or plot; crunching and crumb-scattering is too distracting.
