Directions1.
Combine the vegetables and seasonings in the basin of a 6-quart or larger slow cooker.
Add the chopped garlic, sliced onions, sliced bell peppers, kosher salt, Italian seasoning, dried oregano, and crushed red pepper flakes.
Pour the crushed tomatoes and water over the vegetables and stir everything together until the vegetables are well-coated and the liquid is evenly distributed.
Nestle the uncooked sausage links down into the pepper and onion mixture, ensuring they are mostly submerged.
Place the bay leaf on top.
Cover the slow cooker and cook on LOW for 6 hours or on HIGH for 3-4 hours, until the sausages are fully cooked and the vegetables are tender.
Discard the bay leaf before serving.
Serve hot on crusty rolls or over your favorite pasta.
Garnish with fresh parsley if desired and enjoy!
