Why not use beans, or mushrooms? Or quinoa? Or cauliflower? Or lentils? All cheaper and healthier. And if they don't make sense in your dish...why eat that dish? Food combinations are endless; find something you like made up of the food you want to eat.
I'm not lecturing. I also love meat, but I have trouble wrapping my head around "vegetables and other stuff smashed together to simulate meat". Seems easier to just eat the vegetables.
