Campanha Sauce

Prepare the onion and dice it into very small pieces. You can use a knife, avoiding the use of a food processor.

Finely chop the parsley. Use a generous amount.

Dice two tomatoes, using the proportion of two tomatoes for every large onion used as a baseline.

Chop the green bell pepper. If you wish to alter the flavor, you can add yellow or red bell peppers, although the traditional version only uses green.

Season the chopped vegetables by squeezing the juice of two limes or adding vinegar.

Add a generous amount of extra virgin olive oil.

Finish seasoning by adding a little salt and a little sugar.
