Heat oil in a skillet, add garlic, onion, pepper, carrot & celery. Season with 1 tb tamari. Cook till vegetables are tender. Remove from heat & put in a large mixing bowl. Add mashed tofu. Cut bread into crouton sized pieces & quick fry in remaining oil with rest of tamari, garlic powder & 5 tb nutritional yeast. Add to tofu mixture. Add rest of the ingredients. Mix well. Place in a well oiled casserole dish & press down very well. Bake at 350F for 35 minutes. Allow to cool slightly, then turn out on a plate. Slice & serve. Excellent cold too.
