Tips and Tricks
- You can save yourself prep time and buy sliced pepper and onion strips in the produce section of your grocery store. Keep in mind you will more than likely need more than one package depending on the size your grocer carries.
- Do not substitute frozen peppers and onions. They will get mushy.
- This recipe makes 10 servings, but you can easily cut it in half if you aren’t serving a crowd.
- While I serve it as buns for sandwiches, you can also spoon it over cooked pasta.
- Adjust the seasoning based on the sauce you are using and your personal preferences.
