Preheat the oven to 350?F.
Using a serrated knife, trim the upper quarter off the length of the top of each loaf. Hollow out the center of the loaves, leaving a 1/2-inch-thick shell. Set aside.
Brown the sausage in a large skillet over medium-high heat for about 5 minutes, stirring to break up any clumps. Add the jalapeŇos, bell peppers, and green onions. Cook, stirring, until the vegetables are soft, 3 to 4 minutes. Add the cream cheese, sour cream, and Cheddar and stir until completely melted, about 2 minutes. Add the Essence and remove from the heat.
Fill the hollowed-out bread loaves with equal amounts of the sausage-cheese mixture and wrap each loaf in aluminum foil. Place the loaves on a baking sheet and bake for 1 hour. Remove from the oven, unwrap, and sprinkle with parsley.
Serve warm with chips for dipping, if desired, or cut the bread crosswise into 2-inch slices.
