Instant noodles can be very handy, but you'll often get a better and less salty result if you don't rely on the little seasoning packets that come in the package. Don't throw them away though -- they actually make a fantastic dip for tortilla or potato chips.
The folks over at Lucky Peach have a great suggestion for any seasoning packets you may have left lying around your pantry: mix them up with some sour cream, and use it for dip.
I've tried this one myself, and can vouch for it. It tastes great (especially the "oriental" flavour, although I imagine prawn or chicken would work too) and you don't need to add anything else.
