How to reuse badly cooked chicken I marinated chicken breast cubes in teriyaki sauce for aboutt 1 hour. I then cooked it together with the sauce it was marinating with for about 15 min on medium heat. 

The result was gummy (probably overcooked), hard to swallow chicken that tasted pretty bad. 

I don’t want to just throw it out, but I can’t eat it thr way it is either. Is there a way I can treat it (say even in soup) to make it edible?
Finely chopped or even shredded you could add it to fried rice or noodles (you could use a food processor). The other thing that sometimes works with overcooked chicken is to have it cold, sliced fairly thinly in a sandwich or chopped in a salad, but that may be awkward starting from cubes (unless you like it mixed with mayonnaise).
