"This is a brilliant recipe to use if you want to prep and cook something that you only need to check on occasionally. No slaving over a hot stove for me thanks! This can be used on meats, on sandwiches or with fries like ketchup."

  1. In a saucepan over medium-low heat, combine the cherry tomatoes, red onion, balsamic vinegar, chile pepper, garlic, Italian seasoning, sugar, salt and pepper. Simmer for about 15 minutes, then mash the tomatoes to release the juices. Continue to cook, stirring occasionally, until the sauce is thick, about 45 minutes. Allow to cool, then cover and refrigerate until needed.
