I made that mistake. I thought there was nothing like eggs with chorizo for breakfast when camping up in the mountains --- until after reading the label. Someone told me there's a real good soy chorizo --- called choylizo or soylizo that uses none of what's on that label but tastes the same.
HEB grocery store has more than one brand of chorizo. One (I believe it is the HEB brand) has meat - no "stuff" in it. Still tastes the same. Yummy. I cook it, drain and squish between paper towels to get most of the grease off, add it to taters (cut in little squares)fried with onions and shredded cheddar cheese.
