Can I make a stir fry without broth?

I have steak, and some veggies, and i want to make some kind of stir fry but all the recipes I see are with broth.. I have vegetable oil, some olive oil, cornstarch, soy sauce, teriyaki sauce, maybe some taco seasoning, and of course water... any thoughts? can i just cook the steak in some water and it turn into broth? (I know that's probably stupid, I'm new to cooking)
