First of all, bone and skin your fish and cut into bite size pieces. In frying pan over high heat cook onions, celery, green pepper, garlic in the butter for about 4-5 minutes until onions start to brown and then add tomato and spice. Reduce heat and simmer for 8-10 minutes. Add zucchini or yellow squash and simmer for another 4 minutes and then add Snook and cook another 6-8 minutes until fish will flake with a fork. This stew can be served over or with white rice.
