If you are not a cheese lover or you can't eat cheese, you can make these peppers exactly the same way just omit the cheese. You will notice in my picture that I have Zucchini's shown with the ingredients, with this meal I make Zucchini Fries, it gives you that cheesesteak and French fry meal without all the calories or fat.
1 package of meat I do 3 peppers.
Cut the peppers in half and clean out the seeds and stem, Chop 1 medium white onion, slice 8 oz of white button mushrooms, I get the whole mushrooms, vs. the pre-sliced but either are good. Most recently I have started using baby Bella mushrooms, they have a buttery flavor to them and add a nice flavor to the dish, but either type of mushrooms are good. Finally you will need to decide what type of cheese you want I use Kraft Fat Free shredded cheddar cheese 1 package it is 1 3/4 cup (again the healthy thing going on) but feel free to use whatever cheese you like, plan on using 2 cups of the cheese you choose . It is better if you shred it,
After all this is done you will need to sauté the onions and mushrooms, I do the onions first then add the mushrooms, you can cook them separately because they do cook differently so this will ensure that both are cooked properly, also not everyone likes both so this way you can customize the pepper or sandwich. Once the onions and mushrooms are cooked put them in a bowl and set aside.
You will now need to cook the steak, you can use the same pan that you cooked the mushrooms and onions in, the pan is now seasoned, feel free to add a little Pam so that the steak doesn't stick but it really isn't necessary. On medium high heat place the steak in the pan and cook till brown, it doesn't need to cook long, it will cook in the oven as well so you are just cooking it to get it brown and to tear it apart. You will come up with your own method of breaking the meat up, (I use to wooden spoons, better for my pan) .Once the meat is brown turn off the heat, you will then add the onions and mushrooms and mix it up thoroughly.
Now we are ready to create your pepper steaks. Put your peppers in a 2 inch deep pan I use glass but metal is fine, they need to be hollow side up so you can fill them. First put your cheese at the bottom of the pepper, (remember that you will need to put the cheese on the bottom and the top so use accordingly) then you will divide your steak mixture between the peppers. When they are filled you will need to cover them tightly with foil and bake in the oven at 400 degrees for about 45 minutes. The pepper should be tender, if it doesn’t seem tender enough put back in oven for another 5 to 10 minutes. Remove foil, take the remaining cheese and cover tops of pepper, place back in oven until cheese melts. Remove from oven and you are ready to go.
