Saffron ( half vial), -shredded Saute onion and bell pepper in margarine until translucent. Add water (and some chicken stock) and a hint of garlic. Add celery, parsley, salt and MSG. (Water that comes out of seafood will make another half cup of liquid.) Add mushrooms and clams; cover and bring to boil over medium-high heat. When water comes to rolling boil, put in rice and bring back to LOWEST boil possible. Add saffron; cover pot and don't touch it for 15 minutes. Rice should be cooked, but not split at ends yet --> a little on the dry side. Dump in all the seafood and stir thoroughly. Bring back to a simmer; cover and cook 10 minutes. Might need to cook a little longer with the top off if the shrimp exude a lot of liquid. Check seasonings; can add more butter or pepper. Mom's notes: Might want to add oysters, too. Don't drain the clams! If you use canned mushrooms instead of fresh, add them when you put in the seafood.
