Leafy Greens with Bacon and Onions

I had this delicious side to some chicken this weekend at Stone Brewery and I wanted to try to recreate it. It included kale but I figured since I already had spinach I would substitute that.

Ingredients
Bag of fresh spinach
4 slices bacon
Onion (your choice, diced)
Pinch of brown sugar
Extra Virgin Olive Oil Spray
Salt and Pepper
Optional: Bragg's Amino Acids. (Has a soyish flavor, really good for you if you are trying to lose weight.)
You need a decent sized pan, at least 12 inches around.

I used evoo spray to save on calories and spritzed my pan. Then I tossed in the onions. I cooked them at low-medium heat. After about a minute I added the brown sugar.
While the onions were caramelizing in the pan I placed the bacon in the microwave between sheets of paper towels. I let them cook about 6 minutes then took it out. I broke the slices into small pieces.
I let the onions cook until translucent, occasionally stirring. Then I folded in the spinach and the bacon, letting the spinach cook until wilted.
Add a few shakes of salt and pepper and a couple Sprays of your Bragg's if you are using it and toss one final time before turning off the stove.
Serve immediately.
