Quick French Dip with Green Chilies

I saw my friend, Julia's recipe for Hot Roast Beef Sandwiches with Dip on her blog, Neighbor Julia, and knew that I had to try them.  We've had them a few times since then.  Yummy.  Fast.  And so easy!  

My daughter loved this so much that she took the sandwich that I'd saved for my lunch the next day to school for lunch.  Even my five year old boy liked these (without the green chile).

This is my version of Julia's yummy sandwiches.  

Quick French Dip with Green Chilies

rolls (I love bolillo rolls from Walmart, but any crusty roll will work)
thinly sliced roast beef
provolone cheese
green chile
Au Jus sauce (recipe below)

Cut rolls lengthwise, but not all the way through.  Layer roast beef, provolone cheese, and top with green chile. Place under broiler for a few minutes until cheese is melted.  (Be sure to watch it carefully so the bread doesn't burn.  Bathing your kids while making this meal is not a good idea, unless you like burned sandwiches (not that I would know).)  Dip in Au Jus sauce.

Au Jus Sauce:
In a sauce pan, mix and simmer:
1 can beef broth (or 2 c. water and 2 beef bouillon cubes)
a few dashes Worcestershire sauce
onion (usually use dehydrated)
garlic (fresh or powdered)
salt and pepper
a small pinch of dried thyme
