I got this recipe out of an Italian magazine a couple of years ago and loved it because it goes great with any kind of grilled or roasted meats. Simply brush some thickly sliced onions with olive oil, and season with salt and pepper, place in a shallow pan and cover with foil. Roast for 45 min. at 350 degree's F. Then uncover and roast them for another 40 min.
Once the onions are tender transfer to a platter, and pour your vinegar right into the pan on top of the stove, and on medium heat let it simmer till thick, always moving it with a rubber spatula to scrape up the brown bits.
It didn't take very long to become rich and syrupy. because of the quality of the vinegar.
You'll want to use a good balsamic that has been aged for at least 10 yrs. If you don't want to pay an arm and a leg for a bottle Trader Joe's has a great one( another plug for TJ's!!) but I'm certain you can find some readily available other places.
