The picture is crappy and from my old camera as I posted it a while ago with another "dinner idea" post but, I think it deserves it's own post-link.
-Mix 2 teaspoons brown sugar, 1 teaspoon chili powder and 1 teaspoon ground cumin. Rub salmon with some olive oil then the spice mixture. Bake 10-15 minutes @425 degrees.
My variations on this rub include adding some Old Bay to the mix, or McCormick's freshly ground Italian Seasoning. Sometimes I sprinkle lemon juice on fish before the olive oil and spice rub.
