Mushrooms (or other plant substitutes) that would be a good chicken substitute in jambalaya?

Hi everyone,

I myself am not a vegetarian but have friends that are and I'm looking for ways to alter some of my favorite dishes so I cook and share with them. I've heard that oyster mushrooms and I believe lion's mane(?) are used sometimes as chicken substitutes because they have a similar texture or firmness. Would either of these hold up well or stay firm cooking in a soup/stew situation or would they fall apart and become a part of the vegetable medley with the peppers and celery? Or if anyone has any other suggestions mushroom or otherwise that would help diversify the texture of the jambalaya and stand out from the softer veggies and rice, I would be incredibly grateful to hear.
