Rikkitic - what is your opinion on a vegetarian sausage? Good for you because there is no meat. Bad for you because it is more processed than a chicken nugget.
I really suggest that you check what goes into a chicken nugget, IIRC the one's Maccas sells are marginally okay, if you exclude the batter, deep frying etc. According to Wikipedia they are:
White boneless chicken, water, salt, seasoning (yeast extract, salt, wheat starch, natural flavoring, safflower oil, lemon juice solids, dextrose, citric acid), sodium phosphates. Battered and breaded with water, enriched flour (bleached wheat flour, niacin, reduced iron, thiamine mononitrate, riboflavin, folic acid), yellow corn flour, bleached wheat flour, salt, leavening (baking soda, sodium acid pyrophosphate, sodium aluminum phosphate, monocalcium phosphate, calcium lactate), spices, wheat starch, dextrose, corn starch. Prepared in vegetable oil (canola oil, corn oil, soybean oil, hydrogenated soybean oil) with citric acid as a preservative.
This is food for kids of course, fed to kids by people who might read a food label and decide that they'll be bad for their cat.
The frozen ones sold in big bags cheap at the supermarket are probably worse, they don't even have anything which could be honestly described as "white boneless chicken", but instead scraps of flesh salvaged from slime, reconstituted and shaped to look appealing to innocent children.
I've got a pack of vegetarian sausages in the fridge here - and nope - processed of course, but incomparable to the above.
All depends on how massed produced they are. I assume you are comparing gourmet vegetarian sausages vs massed produced nuggets.
Nuggets basically are chicken, water, salt, seasoning. Vegetarian versions have to replace the chicken with textured vegetable proteins. These are substances don't exist in nature and have to be manufactured in factories. Potato starch, soy protein isolate, wheat gluten, cellulose gum etc are also added. Hence, vegetarian versions of meat products are ALWAYS MORE PROCESSED.
Remember when "pink slime" was just called sausage meat and came in a 500g plastic tube.
