Combine the onion, pepper, ginger, garlic, sugar, cider and cider vinegar in a heavy one-quart nonreactive saucepan. Bring to a bare simmer over medium heat just to soften the mixture a little.
Add the apples, chilies and mint and cook gently for 2 minutes, until the apples begin to soften. Remove from the heat, add 1 teaspoon of salt or to taste. Set aside and keep warm until serving time.
