I use Sambal instead of the Korean pepper paste Gochujang because sambal is easier to find, but if you have Gochujang use that instead of the sambal.
The stickiness and the little spice you get from this dish are amazing, the pop of flavor is surprising, this is a rich dish, but you can definitely add some fresh veggies or a salad to lighten it up a bit. I like to serve this dish with white rice, but you can use brown rice, or any grain you like, I've also had this on top of a salad. Get creative and try whatever combination you enjoy the most.
