Jalapeno Pepper Sauce

5 onions, chopped
2 bell peppers, chopped
12 small tomatoes, chopped
3/4 cup jalapeno peppers, chopped
1 cup granulated sugar
1 cup cider vinegar
1 cup vegetable oil
1 cup water
4 tablespoons salt
4 tablespoons black pepper

Combine all ingredients in a large pot, and simmer for 3 hours. Pour into hot clean jars and seal tightly with lids. Process in hot water bath for 10 minutes. Place jars on towel to cool slowly.

If a more fine-textured sauce is desired, process ingredients in a blender.
