Spinach and Artichoke dip is awesome, but not so much with glass fragments. Publix is recalling some of the dip sold in the refrigerated section in their delis because there's just such a risk. No word as to how the glass fragments could have gotten into the "Artichoke and Spinach Dip" (aren't they saying it backwards?), or even if the glass is even there, but let's not find out the hard way.
If you bought an artichoke and spinach dip with as described on the Publix website (below), throw it out! Or return it to Publix for a refund.
