Eggs - seriously eggs are probably the only food I could consistently eat day after day without ever getting tired of them
Cheese - the heavier the better
Pumpernickel bread - too bad I don't eat it that much on my diet.
But these might come close too
Rare steak
New England Clam Chowder
Crab meat (but I only enjoy cracking it so much and it's expensive, not that steak is really affordable all the time either)
Blueberries
Strawberries
Raspberries
Broccoli, asparagus, brussels sprouts,...
I'd love to say bacon but honestly it's just too greasy. A steak isn't that bad for you if eaten in the proper proportions. You really do have to limit the bacon though. Too much of it can actually make my stomach ache. If I did eat it though, it would need to be moderately to severely soft - I don't enjoy crispy bacon any more (though I used to).
