Deli Style Corn Beef Sandwich

3 lb corned beef brisket
2 tnsp olive oil
2 tbsp brown sugar
2 tbsp cider vinegar
½ cup water
1 small onion, quartered
2 cloves garlic, roughly chopped
Rye Bread
Swiss Cheese
Thick sliced pickles
Coleslaw
Brown Mustard

Preheat oven to 250 degrees.
Heat the olive oil in a heavy pan or braiser. Add the corned beef to the pan, and sear on all sides until browned and crispy.
Add the brown sugar, cider vinegar, water, onion, and garlic to the pan.
Cover with a lid, and place in heated oven.
Roast for about 2½ hours, or until tender.
Let sit for 15 minutes. Let the corned beef cool, or serve it on the sandwich warm. Either way, it's delicious!
Slice the corned beef as thin or as thick as you like, and build your sandwich. I put the coleslaw on the bottom, added a generous helping of corned beef on top of the coleslaw, 2 slices of Swiss cheese on top of the corned beef, 2 thick pickles on top of the Swiss cheese, and a generous dollop of spicy brown mustard to top it off.

we served ours up with some chips and kraut Delicious for lunch or supper if you choose to make the coleslaw yourself it sounds rather easy:
 roughly chopped a half of a small cabbage, shredded a small carrot, a couple of tablespoons of mayonnaise, 1 tbsp. vinegar, 1 tsp sugar, about a tsp of mustard, ¼ tsp salt, and ¼ tsp black pepper, all combined and chilled for about an hour.
