I like HCB's, even the basic mass produced ones (but home made or the fancy bakery ones are nicer), Also like things like Top Top Spicy Fruit bread, Quality Bakers Spicy Fruit Muffin Splits, etc. I'm am absolute sucker for a good Plum Duff (might have to give Clootie Dumpling a go thou), but fruit cake on the other is for the most part a waste of good dried fruit. Generally it's dry and horrible, that being said I have had the occasional nice moist one but very much the exception not the rule.

+1 to micheaelmurfy Coriander has to be up there with "list of plants that deserve to be hunted to extinction"
+1 to eracode Marmalade on toast is great.

Pineapple absolutely belongs on Pizza, as does.. damn near everything.. sorry Freitasm and other Margarita purists you're wrong :-)  I've had many amazing tasting Pizzas with ingredients that would give an Italian traditionalist a heart attack. Pizza has been one of if not my favourite foods since I first tried it as a kid, and while I have my favourite I've never found one I wouldn't eat again. From the mad genius of Tommy Millions to the greasy awesome of a Dominos Double Bacon Cheeseburger, it's all good.

As Geektastic and others have said, Cheese and bread is one of the greatest combinations of all time (and a very old and enduring one!). Cheese on toast, cheese + whatever toasted sandwiches, welsh rarebit, cheese + jam on toast, Cheese + PB on toast, Cheese + vegemite on toast, Cheese spread on toast.. All great.. get in mah belly. Shoutout to MikeAqua for also loving chilli sauce and/or jalapenos and cheese with bread, I had jalapeno and cheese sammies for lunch earlier this week. 

However I'm afraid I'm firmly in the Vegemite > Marmite (be it NZ or British). I don't care if it's not patriotic, the Aussie stuff is just better.

Feta is good

Olives are good

Seafood (including shellfish!) is good but I'm not a huge fan of "raw" fish/seafood dishes. 

Bacon is the supreme food however. All other foods must bow before it. I have a theory I've been espousing for years that bacon is the reason for the whole "middle east crisis". Majority of people there follow religions that ban bacon, that would make even a saint homicidal. If we want to have peace in the middle east, just convert everyone to eating bacon.. Problem solved. I'll take my Nobel prize now :-P
