hmm, my steak meal does make me happy, and it's pretty simple.  i am going to have to try some of the methods posted earlier though!  i get a nice piece of fillet or sirloin from my butcher and just fry it on a hot pan with a little olive oil, usually about 3 minutes a side for fillet, 2 for the normally thinner sirloin.  then while it rests i fry a few mushrooms, peppers and onions.  if i'm having potato or chips those are already cooked, but in recent times i've gone more for salads or steamed vegetables.
i also like a nice tuna steak.  it's not as tasty as the beef, but it makes a good alternative, and apparently it's good for you :)
of course, plugging my les paul via my treble booster into my little 15watt valve amp and wailing for a while also puts a bit of a smile on my face :)
