I don’t have an exact recipe but a rough recipe is

1 onion diced with cooked in a pot with alittle oil and salt for a few minutes until translucent. Add a couple cloves of garlic finely chopped

1 small can of tomato paste stir it around until it begins to cook alittle

Half can of diced tomatoes along with Italian seasoning, couple spoonfuls of ketchup, a little worcester sauce , alittle lemon juice .

Let it simmer with the lid off ( careful of tomato splatter ) for about 20 minutes to thicken. Salt to taste

I didn’t measure anything so that’s the best description I can give. But I like it alot it’s a bit more on the sweet side not savory.
