sauce for stir fry

[OhLittleBitShyOfBethlehem]

I have the veggies and noodles but don't really want to go out and buy a sauce.. any ideas how i could easily add liquid/moisture/taste to the concoction with store cupboard type things?
TIA

soy, honey, ketchup, worcestershire sauce, crushed garlic/ginger?

peanut butter & soy sauce- a satay sauce/type thing!
