very simple meal, but it's so easy that it's worth it. next time i will take the casings off the sausage - i thought after simmering 6 hours they would get soft, but they were still chewy and i peeled them all off anyway. the sauce gets a very strong pepper taste also, so i might cut back on the chopped peppers if i make this again. overall, for the simplicity it tastes great!

Really nothing more than adding peppers, onions, and sauce to some sausages, but after a long soccer practice it sure tasted good!

Found another favorite recipe here! I tweaked this just a tad. While browning the sausage I added the onions & peppers. Then deglazed the pan with a half cup beef broth. Then put it all in the slow cooker with the pasta sauce. The sauce was so good we had to keep dipping our sandwich and fries in it!

I have made similar versions of this recipe before. I use 1.5lbs of spicy italian sausage....bought locally in denver. 3 bell peppers (red,orange,yellow) 2 medium yellow onions. I add lots of fresh garlic. crushed red pepper, italian herbs, salt and pepper. Broil hoagie rolls with cheese and seasoned salt. serve with a slotted spoon. I also carmalized onions to go on the side. pepperocinis too. high on the cockpot 3hrs low 6-8. You cannot go wrong with this wonderful dish. Use over spaghetti/rice the day after.

I will give this five stars, since it is so easy, and tastes good, too. I used a spicier pizza sauce instead of spaghetti sauce, that probably gave it some added flavor. This took much less time in my crockpot, done in about 2 hours on low, then I just kept it on warm until dinner time. I will make these again soon!

I made these for our Super Bowl Party and they were delicious. I used Johnsonville Italian mild and hot sausages (we liked the hot best). I did add a little beef broth and let them cook all day. They were so flavorful and tender.My husband really liked them. Easy and delicious, it doesn't get much better than that! Thanks.

Yum!!! Super simple and super delicious. I think browning the sausage first makes all the difference. I used both Hot & Sweet Italian sausage and let me just say, it's all good! Use whatever type you like. For the best sandwich, toast the buns and melt the cheese a little under the broiler. Add your meat and sauce and get ready to be happy!

This was DELICIOUS and very tasty. My family loved this recipe. It is similar to the Sausage Pepper Sandwich recipe found on this site. The slow cooker really allowed the flavors to blend well. I did make some minor modifications: I added diced garlic, cayenne pepper, and season salt. I used 2tbsp of flour to thicken up the sauce and besided the italian sausage I also added some hot/spicy beef sausages. We will definitely be making this again.
