While we have been waiting for our new stove to be delivered, my DH has been head chef manning the BBQ these past few days.  Thankfully, we have still been having some great food. Grilled chicken with BBQ baked potatoes and salad, Grilled Burgers, and this tasty Grilled Steak Sandwich. This is not a recipe, but a combination of ingredients that just worked.  So, so  tasty.  This makes a quick easy meal if you have the French Bread and Caesar Salad dressing already made. (luckily I had a loaf of French Bread in the freezer)
2 free range inside round sandwich steaks
1 onion halved and then sliced
2-3 Tblsp. butter
salt, pepper, garlic powder
Homemade Caesar Salad Dressing
Aged Cheddar Cheese
Gluten Free French Bread - I used this recipe
Using a heavy duty cast iron pan - place onto a heated BBQ.  Add in the butter to melt, then the onions, sauteing until golden in color.  Remove the onions to a plate and set aside.
Season the steaks with salt, pepper, garlic powder, on both sides.  If using "sandwich" style steaks they will only need a couple of minutes per side on the BBQ.
Toast a couple of slices if Gluten Free French Bread.  Once the bread is toasted, lay down a layer of sliced aged Cheddar Cheese, with a generous topping of caramelized onion.  Top with the seared Sandwich Steak, and drizzle on the Caesar dressing.
DH decided he wanted even more flavor:
Adding a drizzle of Ketchup to his dish - which he said was wonderful.  We do not eat like this very often...but once in a while makes a great treat!
