1/2 small red onion, diced
3/4 cup white wine vinegar

Put corn, red and orange bell peppers, jalapeño and red onion in a large bowl. Bring vinegar, salt, sugar and 1/4 cup water to a boil and immediately pour over relish. Let cool in the fridge for at least 1 hour or up to overnight. Will stay good for up to 1 month.
