I rely on three recipes for high-fat snacks:

• a bacon-cheddar meatloaf
• Pemmican
  
  
• Heroin Wings

I can't post the recipe for Heroin Wings, as it is from Dana Carpender's book, "500 Low-Carb Recipes", so reprinting it would infringe on the author's copyright. I can say, however, that the book is great, and that the recipe is easy to make, very tasty, and quite satisfying.
