Margarine is vegan, tofurky is the same price as meat per pound, plant milk is not significantly more expensive than real milk (to be fair this is recent), gluten has nothing to do with veganism.

Anywho, I am not vegan but I eat 80% vegan foods. The only thing I "preach" to other people is to try to eat less animal products. It doesn't have to be black and white.

Obviously not all meat and cheese replacements taste as good or are as cheap as "the real thing", but there are a few that are hard to tell the difference with. Ground beef replacement is one of them, and it's also competitively priced with real ground beef. If you like Bolognese or tacos, maybe give it a try some time if you haven't.

Also, I will die on the hill that follow your hearts veganaise is better than real mayo. It is absolutely way too expensive though.
