Preheat the oven to 350 F.
Cut the baguettes into large cubes.
Lightly grease a cooking sheet, then place the bread on the sheet.
Bake the bread until it's dry and slightly golden, about 12 minutes.
While the bread is baking, work on the sausage mixture.
In a large pan warm 1 tablespoon of olive oil over medium-high heat and brown maple breakfast sausage.
Once the sausage is browned, remove sausage from pan, but keep the drippings in the pan. If necessary, add up to another tablespoon of olive oil to the pan.
Add in the peppers, onions, and celery. Season with 1 tsp salt, and 1/2 tsp ground black pepper and 1 teaspoon of rubbed sage.
Cook until tender, then add in the garlic.
Let cook for an additional 30 seconds or so, then turn the heat off.
Remove the bread from the oven, then toss the cubes into a large mixing bowl.
Pour in the chicken broth, and let sit for 5 minutes.
After five minutes, add in the egg, sausage, remaining seasonings, and vegetable mixture.
Mix until everything is well combined and pour into a well-greased 9x13 casserole pan.
Bake uncovered for 50-55 minutes, or until the stuffing is a beautiful golden color.
