1. Saute onions and peppers in a little olive oil in a skillet over medium heat. Season with salt and pepper.
2. Mealwhile, pour 3-4 beers into a large stock pot and bring to a boil. (we recommend doing this outside if your grill is large enough or has a burner, otherwise make sure to use the exhaust fan!)
2. Prick sausages and dump into the beer and let them boil for 10 minutes - 15 minutes or until cooked through. You can leave them simmering until you are ready to grill.
3. Turn your grill or grill pan up to high-heat. Sear sausages to crisp up the skin and get them to your desired color on all sides(watch closely so they don't burn).
4. Serve them on hoagie rolls with onions, peppers and a selection of mustards.
