For easy clean-up, place a cooking bag in a slow cooker.

In a large skillet over medium-high heat, brown sausage in oil; drain. Transfer to a 5-qt. slow cooker. Add the spaghetti sauce, peppers, water, cheese, oregano and basil. Cover and cook on low for 4 hours or until sausage is no longer pink.

Slice each French bread lengthwise but not all of the way through; cut each loaf widthwise into five pieces. Fill each with sausage, peppers and sauce.
