Steak & Onion Sammy's

This recipe, I once again cannot take credit for, it's actually a weight watchers recipe (shhhhh... I won't tell). My younger kids are not big fans of the onions on the sandwich but they do love the steak, so I will usually have some sort of veggie side dish so they are not just eating beef for dinner.

3 Large Onions (if you can find Vidalla's - they are the best)
1 Flank Steak
Salt & Pepper
1 T. Balsamic Vinegar
2 T. Sugar
Marble Rye Bread (or regular rye)
Dijon mustard
Lettuce & tomato
Extra Virgin Olive Oil

Cut the onions in half then use a mandolin (or your super handy knife skills) to slice the onions into paper thin slices. Heat a tiny amount of the olive oil (or you can even use cooking spray) over medium-high heat. When the oil is hot add the onions, sugar and 1/2 t. thyme. Allow to cook until golden brown and caramelized.

While the onions are cooking:
Pre-heat the oven to Broil or start up your BBQ. Season the steak liberally with salt & pepper (and maybe a dash of cayenne pepper is you like a little heat). Cook the steak for about 7-8 minutes per side for medium doneness.  When the steak is cooked, let it rest on the cutting board for at least 5 minutes so the juices don't run when you slice it.

Once the onions are golden add the balsamic vinegar and a dash of salt & pepper. Cook until all the liquid has evaporated.

Slice the lettuce & tomatoes and thinly slice the steak. 

Layer the steak, onions, lettuce & tomato on the rye bread that has been slathered with a thin layer of Dijon mustard.

makes 6 hearty sandwiches - depending on size of steak.
