It's pretty easy to replace chicken since it tastes like nothing on its own. Most of the flavor is in the spice and seasoning so I just use those spices and seasonings on whatever protein I'm cooking it.
A lot vegan stuff online tries to be "healthy" which is why it's associated with being bland but there's lots of stuff like fries and mushroom gravy, apple pies, pancakes, chips, fruit or soy based ice creams, pizza and panzerotti with plant based cheeses (much less oily too), things like chocolate, though some substitutes can be expensive. I don't even notice the change but it was really difficult when I was younger and thought I had to eat only stuff like salads.
Get soy/soya chunks from an international section or store, they need a tutorial on how to make them but they're extremely cheap and shelf stable. They just need to be soaked and squeezed a few times to meditate aftertaste but I never really cared about it lol. I fry them to make burritos with a mayo (no egg) and siracha base. More dark texture than tofu.
