I sort of invented this and didn't measure, but think these are about what I did. Serves 4.

3 med. onions, halved & sliced thin
Olive oil
2 cloves of garlic, sliced thin
Handful of fresh thyme branches (or about 1/2 teaspoon dried)
Balsamic vinegar
Honey (a tablespoon or so)
1 large apple, quartered and sliced thin
Bag of fresh baby spinach (10-12 oz.)

Heat some olive oil in pan, I used non-stick. Cook at medium or so until starts to turn brown. Add oil if it dries out. This may take 20 minutes, keep an eye on it. Stir in garlic and lay fresh thyme on top, and press down (or stir in dried thyme.) Cook, stirring, 5 minutes or more.

Add a little more olive oil, the balsamic vinegar and honey. Stir. Mix apple and spinach in large bowl and pour warm dressing over it, toss.
