"My Hero" Sandwiches

This is an upgraded version of a super-simple sandwich recipe.  Matt and I made some changes, and I am so glad we did!

Ingredients:

French Hero Rolls (we used ciabatta)
~1 lb. cheap steak
Worcestershire sauce
season all
thick sliced mozzarella
olive oil
1 red pepper, sliced thinly
1/4 of a red onion, sliced thinly (I would probably do half of that...it was pretty onionly)
~6 fresh mushrooms, sliced
salt and pepper to taste
white wine vinegar

For the Sauce:
1/2 cup mayo
2 tablespoons prepared horseradish sauce (I have the zesty instead of hot)
1/4 teaspoon ground mustard
1/4 teaspoon salt
2-3 garlic cloves, minced (I used the garlic press)

Tenderize the steak by forking or using a tenderized with tines.  Pour Worcestershire sauce on it.   Marinate for about 15-20 minutes (or as long as you have)

Make the sauce by mixing or whisking all ingredients together.  Then chill in the refrigerator until you are ready to make up the sandwiches.

If you are lucky, you can have your husband grilling the steak while you are working on the veggies.  If not, you will have to do them in stages or broil the steak.  When it is the done-ness that you like, let it rest for about 5 to 10 minutes.  Then slice it very thinly across the grain.  I think of it as the slanting or angled cut.

Heat the olive oil in a skillet on medium heat.  Cook the onions for about 5 or so minutes.  Then add the red pepper.  Cook for about 5 more minutes.  Add the mushrooms and cook until they start to shrink and turn brownish.  When it gets dry, add a splash of white wine vinegar and add the salt and pepper to taste.  Cook until the veggies are the softness that you like.  Cover to keep warm. 

Now that all the parts are cooked, it is time to assemble the sandwiches.  We got two big ciabatta sandwiches from it.  Put a thick layer of the mayo mix on the bottom, and if you like, put a little on the top too.  You might want to taste it to see how hot it is for you.  Lay the rolls on a broiling rack with the insides up.  Put the steak slices on the bottom of the roll, then the mozzarella on top of the steak.  On the top, add the vegetables.  Broil in the oven for 3 to 5 minutes, until melty and delicious. Be careful to watch it so it doesn't burn!  After pulling them out of the oven, let them rest for a minute, until you can handle them.  Then put them together, slice them in half at a fancy angle, and serve. 

This is probably the best sandwich recipe we have ever made!
