Apples 'n' Onions

I have read all of Laura Ingalls Wilder's books many times.  Most of Farmer Boy, about her husband's childhood, centers around food.  One time, I decided to try to make pan-fried apples & onions.  Turns out, it's really good.  This side goes with any meat.  Or, you could serve it as a kind of cooked salad.  Maybe even as a brunch go-with.  The sweetness you get with caramelized onions is enhanced by the apple juices.  For a more savory zing, cook them in bacon drippings instead of butter.

2 medium yellow onions
3 apples about the same size as the onions.  I would use a semi-tart variety like Gala or Fuji
2 Tb butter

1.  Slice onions into rings.  Core apples and cut in half.  Cut into thin slices.

2.  Melt butter in a large frying pan on medium heat.  Cook onions until soft, about 5 minutes.  Add apples and continue to cook until tender, at least 10 minutes.  Serve hot
