Pepper Onion Relish

Chop the white onions and sweet red peppers into small, uniform pieces, approximately ¼ inch, and set aside.

Chop the green peppers into small, uniform pieces matching the size of the other vegetables, and combine with the onions and red peppers in a large bowl.

Transfer the combined vegetables to a large, heavy-bottomed pot or Dutch oven.

Add the white vinegar, sugar, and salt to the pot and stir until the sugar begins to dissolve.

Bring the mixture to a gentle boil over medium-high heat, stirring occasionally to ensure even cooking.

Reduce heat to medium and simmer uncovered, stirring occasionally, until the vegetables are tender and the mixture has thickened slightly, approximately 40 minutes.

Test the relish for doneness by checking that the vegetables are soft and the syrup has slightly reduced and coats the back of a spoon.

Remove from heat and allow to cool slightly before transferring to sterilized jars for storage or serving dishes as desired.
