Preheat oven to 350.
Using a sharp knife, cut the sausages into quarters, lengthwise. You should have sixteen- 4”5” long, narrow pieces.
In a small sauté pan, melt the bacon fat over medium heat. Cook the onions, peppers, and celery for 3-4 minutes. Add the garlic and Creole seasoning and cook for 3-4 more minutes. Remove from the heat and cool this mixture.
Spoon one teaspoon of the vegetable mixture down the center of each crescent roll. Place a piece of sausage on each prepared crescent roll, and wrap the dough around the sausage.
Bake until golden brown.
