The Quorn chick'n cutlets are really good, but they're made with eggs, so obviously they're not vegan. That said, they're great for basically any dish you'd use chicken for.
Also, vegan sausage is healthy, and basically one of the only substitute meats that are suitable, since sausage is just filler and spices anyway. I mean like the crumbly kind you can throw in a skillet with eggs and peppers. Worth a try!
It's amazing how many meat substitutes have eggs, cheese, or milk. That said, almost every substitute meat product tastes different, and it's worth trying a variety of stuff. There are some really great veggie patties out there (and I bet the ones with cheese in them are even more delicious!)
However, substitute cheese is something I cannot handle yet. Nutritional yeast does in a pinch for cheesy cravings though.
