For the vegan "chicken":
In a medium pot, combine hot water with spices and veggie broth. Soak the TSP slices in this liquid for at least an hour.
In a nonstick pan, over a medium heat, cook the TSP slices on both sides, 3 to 5 minutes each, until lightly golden. Set them aside.
Make the cacciatore sauce:
Heat the olive oil in a large skillet, over medium heat.
Add the onion and cook it for a few minutes, until translucent. Add the garlic and saute for a few more minutes.
Add the mushrooms, carrots, bell peppers and cook them for about 10 minutes.
Add the TSP slices, wine, basil leaves, oregano, and olives. Let them simmer for a few minutes. Stir everything to combine and continue cooking. Add crushed tomatoes, chili powder, salt and pepper and stir in the tomato paste. Cook for 5 minutes, stirring occasionally to incorporate the flavors. Top with some fresh herbs and serve.
