If I inadvertantly forget to wash and said the bracha hamotzi, and have just broken the bread, but not eaten yet, what should I do next?
In the Aruch HaShulchan OH 167:17
he writes that if one forgot, said the beracha of hamotzei before he made netilas yadiim, he can wash his hands and the washing is not considered an interruption, and therefore he does not need to repeat the hamotzei after he washes
since the from icar hadin you could eat less than a cazait without netilat iadaim, I think you could eat less than cazait and then do netilat iadaim. but I'm not sure about the beracha
