Is sauce on the chicken or meat enough not to be considered roasted or do you need water?
There is controversy among the Poskim if a little water will also be considered like a pot roast which is considered like roasting, or do we say that since it has some water in it, it is not a pot roast. Using sauce would be similar to this, if it is only a small amount of sauce, it wold be similar to this controversy, however if it is a significant amount of sauce then it would be permitted.
