HOW TO MAKE PHILLY CHEESESTEAK MEATLOAF :
Step 1: Prepare the oven. Preheat it to 350 degrees F or 175 degrees C.
Step 2: Heat oil in a skillet over medium heat. Saute the onions and peppers until soft and translucent.
Step 3: Transfer the onion and pepper mixture to a large bowl and pour in the milk and add in the meat. Blend with your hands until incorporated.
Step 4: Use a cooking spray or butter to grease a loaf pan. Add half of the mixture and top with 4 slices of cheese. Add the remaining meat mixture on top.
Step 5: Bake in the preheated oven for about 30 minutes or so.
Step 6: Take the meatloaf out of the oven and add on top the remaining cheese and parsley. Bake for 10 to 15 minutes or until the cheese has melted completely.
Step 7: Allow cooling on a wire rack at room temperature.
