High protein with fairly low fat content.
Easy to prepare (one minute in the micro-nuker)
Great alternative to traditional breakfast meats like sausage or bacon.
Can be a bit pricey. Up to $4 or more for a box.
Sodium is high.
Does not taste like pork sausage. In fact, it's kinda bland. I use hot sauce to add zip.
As I said, I discovered these when I was a vegetarian and have continued to use them long after I had gone back to eating meat. It's not something that I eat every morning, but they are a good way to add variety to a breakfast and get good nutrition without loading up on animal fats.
