FETA RULES! Love a good Slouvaki!
Love Goat cheese also..
Here's a good recipe for goat cheese and Feta:
Get yourself a nice prime beef tenderloin filet (I like dry aged) and cut a pocket into it, then mashed together 3 parts goat cheese to 1 part Feta and season to your liking with fresh herbs, such as thyme, or Rosemarry. Stuff the fillet with the mixture, but do not over stuff! Wrap the stuffed filet with bacon and pin the bacon down with a couple tooth picks or butcher's twine/rope. Grill, or broil to your desired likeness..
Also, if you really want to go all out you can accompany the steak with a nice sauce. Easiest way would be to ask your butcher for some beef scraps or some beef broth they may have. Cook down this broth so that it's Nape, meaning will coat a spoon and hold a line after a finger is run over it. When your at this point, here's the fun part, add some of those spicey jams or jellies they have at the grocery store, or at an Asian market, to the sauce. This will add spice, and some sweetness that will off-set the bold, earthy, salty flavors that come from the steak, goat cheese and feta and balance it all out. I also suggest some garlic masked with it.
A good wine would be Rosemount Estate Shiraz, I like 99'
I've done this at many different restaurants as a special and sold out every time.
Remember, cooking is about tasting and what YOU like. If you taste somthing that you've cooked and say "wow, thats awesome", chances are everone else will like it too. So experiment with that spicey jam sauce and see what ya think.
