Creating Italian Sausage Peppers and Onions is straightforward if you follow these steps:

1. Prepare the Ingredients: Slice the sausages, onions, and bell peppers. Mince the garlic and set aside.
2. Cook the Sausages: In a large skillet over medium heat, add the olive oil. Once hot, add the sliced sausage and cook until browned, about 5-7 minutes. Remove from the skillet and set aside.
3. Sauté the Vegetables: In the same skillet, add the sliced onions and bell peppers. Sauté for 5-7 minutes until they begin to soften.
4. Add Garlic and Spices: Stir in the minced garlic, oregano, basil, salt, and pepper. Cook for another 2 minutes, allowing the flavors to meld.
5. Combine Sausage and Veggies: Return the browned sausage to the skillet, stirring to combine with the vegetables.
6. Add Tomatoes (Optional): If desired, pour in the diced tomatoes and stir. Allow the mixture to simmer for an additional 10 minutes, letting the flavors blend together.
7. Taste and Adjust: Taste the dish and adjust seasonings if necessary, adding more salt or pepper.
8. Garnish and Serve: Once cooked through, remove from the heat. Garnish with fresh basil leaves before serving.
