I cracked open the last of the bags and have been sampling them. Here's my opinion of the rest of them:
Plain TVP: not much flavor, kind of tastes like Fiber One cereal.
Chicken Bits: unlike the Chicken Chunks, this one is crunchy and lacking in flavor. This one has a bit more flavor than the plain TVP, but not by much.
Beef Chunks and Beef Bits: both taste the same, which is to say they are so mildly flavored, they aren't much better than the plain TVP.
Bacon Bits: these taste quite good and are not crunchy like most faux bacon bits. These are kind of soft, like real bacon.
Taco Mix: it tastes like taco seasoned TVP, which is to say it has a strong cumin flavor with just the slightest hint of heat (not much).
Sloppy Joe Mix: Overpowering cumin flavor with a bit too much salt. Perhaps cutting this one with a little regular TVP would help tame it. Or just go with the Taco Mix, which is very similar but not so strong.
As a side note, I tested the flavor of the ham bit and bacon bits compared to my Bac'Uns (name brand) faux bacon bits. I preferred the Mother Earth flavors over the Bac'Uns, but just by a little. As a reminder about the Mother Earth brand, the ham bits are crunchy and the bacon bits are chewy. Both taste great, it just depends on what texture you might prefer.
One last thing for anyone considering ordering from them: with each order, they offer to give you 2 samplers for free. The samples are 1/2 cup in size, which is a decent bit.
Conclusion... my favorites, in this order: chicken chunks, ham bits, sausage bits, bacon bits, pepperoni bits, taco mix. I don't really recommend the other flavors.
