Can you cook frozen chicken with no goblets in slow cooker?

Although I have never used "goblets" in my slow cooker I imagine they would save some time in that they can be used instead of a serving platter, however I would recommend a "Pyrex" brand to withstand the heat and prevent the glass from shattering which would make for an unpleasant meal. I also expect that indigestion would be the least of your problems.
