If you have a good piece of steak, yeah, salt and pepper. Wait until its at room temperature.
If you have an OK piece of meat, I usually marinade it with some stuff that costs $1 for the pack, and you can usually use 1/2 the packet per piece of steak.

Put the steak in a large ziplock, add some of that powder (half a pack) add the canola oil and white vinegar and some water and let the steak sit for a bit in that bag (maybe an hour or more). Read the directions.
