Fast food is just that. It makes no excuses for being "fast" and certainly does not try to pass itself off as gourmet cooking. But, even still, people like to be given a choice and like to think they are getting what they asked for, both in terms of looks and taste.
Thus, the Subway Cold Cut Combo offers the hungry fast fooder the alluring option of not having to choose a particular type of cold meat, but rather they can have all three on offer. The sandwich consists of ham, salami and bologna together with some greens.
This sounds ideal for a nice wholesome on-the-go meal with plenty of taste and choice. Until you read the fine print that is. The cold cuts in the Cold Cut Combo are listed as all "turkey based meats."
In other words they are turkey meat that has been ground up, mixed with a bit of the associated meat and reconstituted into what looks like, and mostly tastes like, the associated meat. But most of it is turkey.
However, this should not be too alarming since, for instance, salami itself is a seasoned sausage made up of ground beef and other ingredients. Although salami can also be made from pork, there is certainly no reason why it could not be made from turkey.
At least Subway is telling you that your cold cuts are actually turkey. Others may be doing the same thing without disclosing the truth!
