Philly Cheese Meatloaf

I found this on my friend’s Facebook post. Thought I’d make the U.S. conversions for everyone and save it here for all to enjoy!
so ;;;i Made this tonight as written. It was delish! Will become a regular in our rotation. Cheers.

Ingredients :

• 2 tablespoons butter
• 1 small yellow onion diced
• 1 small green bell pepper diced
• 8 ounces brown mushrooms minced
• 1/2 teaspoon Kosher salt
• 1/2 teaspoon fresh ground black pepper
• 2 pounds lean ground beef 80/20 or 85/15
• 2 tablespoons ketchup
• 2 tablespoons Worcestershire sauce
• 2 eggs
• 1 cup panko breadcrumbs
• 8 ounces Provolone Cheese Slices

Directions :

Step 1 :

Preheat the oven to 375 degrees and spray a large loaf pan with cooking spray.
In a large skillet, add the butter and the onions and bell peppers, mushrooms, salt and pepper.

Step 2 :

Let brown for 1-2 minutes before stirring, then let brown for another 1-2 minutes before stirring again.
Let cool for five minutes.

Step 3 :

In a large bowl add the ground beef, ketchup,Worcestershire sauce, eggs, panko breadcrumbs and the cooled vegetable mixture.

Step 4 :

Add half the mixture to your loaf pan then add half of the cheese to the middle of the pan in a 2 inch wide section (I cut the slices into thirds for the right width).

Step 5 :

Cover with the rest of the meat and form into a rounded top loaf shape.
Cook for 40 minutes, then pull out of the oven, cover with remaining cheese and put back in.

Step 6 :

Cook for 15-20 minutes, then let rest for 10 minutes before cutting.
