Stuffed pepper stuffing without the peppers

Someone requested that I make the following recipe for stuffed pepper stuffing, without actually stuffing the peppers:

Brown 2 pounds of ground chuck in a cast iron skillet.

Now, the recipe says to saute chopped onions, celery, and green pepper in butter, until they are soft.  I don't like green peppers, so I was going to omit the green pepper.  However, I found a prepackaged mix in the produce section, called "Louisiana's Choice Creole Seasoning Mix", which contained finely chopped onions, celery, green pepper, shallots, parsley, and garlic, already mixed together.  I wanted to save some time, so I used that.

So, in a separate skillet, I sauteed the chopped veggie mix in butter, until they were soft.

In a bowl, I shredded some hamburger buns; The recipe called for hamburger buns, but personally, if I were to do this again, I would shred saltine crackers instead.

Then poured in just enough milk to make the bread moist, but not wet.  

Added parmesan cheese to everything.

Then mixed it all together in a casserole dish.  Crushed some saltine crackers and sprinkled the crumbs on top.  Added more parmesan cheese, and put some dots of butter on top.

Into the oven at 325 degrees, until done.

It tasted good, but I definitely would like it better if it were all cracker crumbs, instead of the soft bread.  

Something about ground beef on soft bread doesn't sit well with me.  That's why I never eat the bottom bun of a hamburger.
