Yes- steaks-- cooked Sous Vide style.  I know- sounds silly because you have a perfectly good grill - but Sous Vide style allows the steak to be cooked perfectly throughout - and provides a far better moisture than steaks that are grilled or fried.

The Rub

Equal parts:

Kosher salt, brown sugar, Paprika, and 1/2 part pepper - now many people find this a bit spicy so some just prefer to season the steak with salt and pepper as below.

Rub both sides of the steak with the rub.

Alternative Rub for those who like simple:

Sometimes I don't feel like that rub and I simply season the steaks with salt and pepper.

Place the steak in a vaccum seal bag.

Cook the steak in the Sous Vide water bath at 136 degrees for 45 minutes (per inch thick)

Here is the great thing: if you have something else to do- or the party isn't ready to eat steaks you can leave them in the Sous VIde waterbath - they won't get overdone. 

Once you are ready to eat the next step is simply to sear the meat. 

Heat a grill, or a grill pan to high heat -

Grill 2 minutes a side to put those nice grill marks on the steak - you can use your indoor grill, an outdoor grill, or Big Green Egg
