1.Heat the oil in a pan over medium heat.

2.Add the finely chopped onions to the pan and sauté until they become translucent and slightly golden, about 5-7 minutes.

3.Stir in the chopped tomatoes and cook for another 5 minutes until they soften.

4.Add the tomato ketchup, salt, and sugar to the pan, mixing well to combine all the ingredients.

6.While the mixture is cooking, toast the bread slices in a toaster or on a skillet until golden brown.

7.Once the onion-tomato mixture is ready, spread a generous amount on each slice of toasted bread.

8.Top with fresh herbs if desired, and serve immediately.
