Chicken & Sausage Gumbo

I hope I have some New Orleans readers out there b/c I have a question. What is the difference between a Gumbo & a Jambalaya? We love both, but I was trying to find recipes for smoked sausage (it was on sale, I stocked up) & this gumbo came up and it made me wonder, what is the difference really?

Chicken & Sausage Gumbo
Yield
6 to 8 servings

Ingredients
1 (16-ounce) package Cajun-style smoked sausage, cut into 1/4-inch slices
2 celery ribs, chopped
1 medium onion, chopped
1 medium-size green bell pepper, chopped
4 cups chopped cooked chicken
1 (32-ounce) container chicken broth
1 1/4 cups uncooked long-grain rice
1 tablespoon Cajun seasoning
Garnish: chopped fresh parsley
Preparation
Cook smoked sausage in a Dutch oven over medium heat, stirring constantly, 3 minutes or until browned. Add celery, onion, and bell pepper, and sauté 6 to 8 minutes or until vegetables are tender.

Stir in chicken and next 3 ingredients; bring to a boil. Cover, reduce heat, and simmer 45 minutes or until rice is done and liquid is absorbed. Remove from heat, and let stand 10 to 15 minutes before serving. Garnish, if desired.

If you omit the rice from this or use a brown rice, this is a very healthy meal. I used turkey smoked sausage in mine. But I made it unhealthy by using a box of Zatarain's Garlic & Herb rice. But wow, it was so good! I had more gumbo than rice, so I froze half of the recipe for post-baby time.
