Here's a basic recipe to make your own seitan: https://www.vegetariantimes.com/recipes/homemade-seitan
You may be able to find ready to eat/prepare seitan in your local supermarket. It's pretty much used as a meat substitute. I've had buffalo seitan instead of chicken wings and they were really good. I think the best way to cut down your red meat intake is to just substitute it with naturally great tasting food like beans, pasta, fresh vegetables, etc. Dipping peppers, carrots or celery into freshly made hummus is a great meat alternative, as is a stir-fry with eggplant, onions, peppers, and tofu. - Thanks for reading
