When sous viding food, it almost always follows the same process.
The first step is to trim and season your food, just like you normally do in traditional cooking. Many of the same seasonings can be used, including spice rubs and most herbs. I usually salt my food before sous viding it, though many people omit it for longer cooks. The only big difference is that aromatics like raw garlic and onion are usually not used in sous vide because they will not break down with the lower temperatures used in sous vide.
