In a saute pan over medium heat, add in olive oil. Add in minced garlic, and stir about 30 seconds until fragrant. Add in Italian sausage, breaking it apart with a wooden spoon into large chunks.
When the pork has turned golden brown on the outside, add in the roasted red pepper, fresh bell pepper, onion, and basil. Continue to cook until the onions have softened.
Add in the pasta sauce and bring to a simmer for 5 minutes, or until the pork sausage is cooked fully.
Cut the end off of each baguette. If you are using a large baguette, slice in half. Using a muddler, or a wooden spoon with a thick handle, press it into the middle of the bread down to squish down the middle to create a hollow space.
Spoon the pork sausage mixture into the hollow center. Wrap with parchment paper and serve immediately.
