They're clearly marked if they're vegan (and the website states whether they are or not, and lists the ingredients as well). They were only $4 (!!) when he picked them up for me--I'd imagine the price'll vary, depending on where you track them down. And they feed a small army (and for cheap!). That's my favorite part. There's about 9-10 servings per "entree," so if you make one on a Sunday, say, you'll be hooked up with lunch the whole rest of the week.
They's good stuff, peoples. Check them out.
