Creating Slow Cooker Sausage and Peppers and Onions is simple if you follow these steps:

1. Prepare the Ingredients: Slice the bell peppers and onion into thin strips. Mince the garlic.
2. Brown the Sausage: (Optional) In a skillet over medium heat, brown the Italian sausage for a few minutes to enhance flavor. Drain excess fat if necessary.
3. Add to Slow Cooker: Place the sliced bell peppers, onions, and minced garlic into the slow cooker.
4. Add Sausage and Tomatoes: Place the browned sausage on top of the vegetables, then pour the diced tomatoes over everything.
5. Season: Sprinkle Italian seasoning, salt, and black pepper over the mixture. Drizzle with olive oil if desired for added richness.
6. Cook: Cover the slow cooker and set it to low for 6-8 hours or high for 3-4 hours. Stir occasionally if possible, but it’s not necessary.
7. Check for Doneness: Ensure the sausage is cooked through and the vegetables are tender. The flavors should meld beautifully.
8. Serve: Once cooked, stir the mixture gently and serve hot.

This straightforward approach will yield incredible results without much effort!
