Barbecue Sauce, fruit-sweetened

This is delicious, and it's GAPS/SCD friendly! Makes about 2 cups.

2 medium-large ripe tomatoes
1/2 cup cider vinegar
2 small-medium apples, with skin (preferably a sweet variety like macintosh)
1/2 tsp. salt
2 large garlic cloves
1/2 small onion, sliced
1/2 red chile pepper, seeded

Combine all ingredients in a saucepan over high heat; when mixture boils, reduce heat and allow to simmer uncovered for an hour or so, until vegetables/fruits are super soft, and the liquid has reduced. (For even thicker sauce, simmer for a longer time.)

Blend the sauce smooth using an immersion or regular blender.
