This recipe is from my sister-in-law Marsha, who is amazing in the kitchen.
2-3 pounds of sweet Italian sausage. Use sausage from a real Italian store if possible, you will taste the difference.
2 jars of spaghetti sauce, to cover. Use your favorite brand and flavor.
Sliced green, yellow and red peppers. At least 2 of each, quantity depends on how many people you are feeding, and how much you want to eat.
2 large onions, sliced. More if you like.
Italian seasoning (she didn’t give quantities, but I’d start with two tablespoons)
Optional: shredded carrots, garlic.
Also optional, but a good idea: add meatballs, because why not? (not the pre-cooked kind)
Add all ingredients to crockpot, cook on low for 8 hours.
