Instructions

Place a large skillet over medium-low heat. Add the water and half of the ¼ cup olive oil. Arrange the Italian sausage links in the skillet, poke a few small holes in each sausage with a toothpick, cover, and cook for 3–4 minutes.
Flip the sausages, poke a few additional holes, cover again, and continue cooking for another 3–4 minutes to help cook the sausages evenly.
Once the water has evaporated, add the remaining olive oil and reduce the heat slightly. Brown the sausages on all sides, turning occasionally, until golden and fully cooked. Italian sausage should reach an internal temperature of 160°F (71°C), while poultry sausage should reach 165°F (74°C). Transfer the sausages to a plate and allow them to cool slightly before slicing.
Keep the skillet over low heat and add the sliced bell peppers to the remaining olive oil and sausage drippings. Stir well and cook for approximately 3 minutes, allowing the peppers to begin softening.
Add the sliced white and yellow onions to the skillet. Stir everything together, cover, and cook for 6–7 minutes, stirring occasionally, until the onions soften and the peppers become tender.
Remove the lid and season the vegetables with garlic powder, red pepper flakes, salt, and black pepper. Slice the cooked sausages into manageable pieces and return them to the skillet. Stir to combine and cook over low heat for another 3–5 minutes until the sausage is heated through and the vegetables are fully softened.
Prepare the fennel mustard slaw by combining the thinly shaved fennel, chopped fennel leaves, fresh basil, and flat-leaf parsley in a large mixing bowl.
In a separate small bowl, whisk together the chopped capers, Kewpie mayonnaise, Grey Poupon mustard, stone-ground Dijon mustard, whole grain mustard, champagne vinegar, olive oil, minced garlic, salt, and black pepper until well combined.
Pour the mustard dressing over the fennel and herb mixture. Toss gently until everything is evenly coated. Set aside until ready to assemble the sandwiches.
Using a sharp knife, cut an opening along the top of each sandwich roll, creating enough space for the filling without cutting completely through the bread.
Generously fill each roll with the warm Italian sausage, sautéed bell peppers, and onions. Spoon the fresh fennel mustard slaw over the top of the filling.
Serve the Italian Sausage & Pepper Rolls immediately while the filling is warm, the bread is fresh, and the fennel slaw remains crisp.

Notes

Sausage options: Use a combination of mild and hot Italian sausage for balanced flavor. Choose all mild sausage for a less spicy sandwich or all hot sausage for extra heat.

Bell pepper variations: Use any combination of red, orange, yellow, or green bell peppers. Red, orange, and yellow peppers provide a naturally sweeter flavor.

Adjust the heat: Reduce or omit the red pepper flakes for a milder filling, or add extra flakes for a spicier version.

Mustard variations: Adjust the proportions of Grey Poupon, stone-ground Dijon, and whole grain mustard according to your preference. Additional mustard creates a stronger, tangier slaw.

Lighter slaw: Reduce the Kewpie mayonnaise and increase the champagne vinegar or fresh herbs for a lighter, brighter dressing.

Fennel substitute: Replace shaved fennel with thinly sliced cabbage for a crunchy alternative. The mustard dressing pairs well with either vegetable.

Best sandwich rolls: Choose sturdy Italian rolls or hoagie rolls that can support the juicy sausage filling and slaw without falling apart.

Toast the bread: Lightly toast the sandwich rolls before filling for extra texture and to help prevent sogginess.

Make-ahead filling: Cook the sausage, peppers, and onions in advance and refrigerate them in an airtight container. Reheat thoroughly before assembling the sandwiches.

Make-ahead slaw: Prepare the shaved fennel and herbs separately from the mustard dressing. Combine shortly before serving to maintain the fennel’s crisp texture.

Storage: Store leftover cooked sausage and pepper filling in an airtight container in the refrigerator for up to 3–4 days. Refrigerate the fennel slaw separately and keep the rolls at room temperature according to their freshness.

Reheating: Warm the sausage and pepper mixture gently in a skillet over low to medium heat until thoroughly heated. Add a small splash of water if needed to prevent drying.

Freezing: The cooked sausage and pepper filling can be frozen in a freezer-safe container for up to 2–3 months. Thaw overnight in the refrigerator before reheating. Prepare the fennel slaw fresh for the best texture.

Serving suggestions: Pair these sandwiches with potato chips, roasted potatoes, pickles, a fresh green salad, or other game day appetizers.

Assembly tip: Add the fennel mustard slaw immediately before serving to prevent the bread from becoming soggy and to preserve the slaw’s crunch.

Nutrition information is estimated per sandwich based on 10 servings, standard Italian sausage links, medium-sized sandwich rolls, and an even distribution of the vegetables and slaw. Actual values vary depending on sausage size, bread, and ingredient brands.
