Meatball Sub Stuffed Burgers

My grandma’s kitchen was full of all sorts of gadgets. She loved trying new things, so when she saw the latest kitchen gadget, she had to have it. I am so like my Grandma because one day as I was cleaning her kitchen, I saw one that I just had to have.

The “Stufz Burger Press”. At first I wasn’t quite sure what I was going to do with it. But at the same time, I felt like there was so much I could do with it!

I thought stuffing it with mushrooms could be good, or maybe stuffing a burger with bacon. Why not add to mac n cheese to the middle? Then I thought cheese had to be added to the center as well. As I was thinking about cheeses, I came up with this recipe.

Honestly I thought it was brilliant. (Spoiler alert: it was) Meatball subs are so delicious, but I never order them because they are just so messy. The meatballs never stay on the sub. Every time you take a bite they fall out in every direction. I thought if we could make the meatball into one piece — a burger — that problem would be solved!

So, I got to work. I made the meat with this meatball recipe I found on Pinterest.

The contraption was a little hard to use, so I watched this video on Youtube to help me understand. It was very helpful because it was from the inventor himself.

I used sandwich sliced mozzarella cheese, but I wish I used shredded because I think it might have worked better.

Once the burger was stuffed, I threw it on my George Foreman grill and cooked them for about 10 minutes. Cook time will vary depending on your preference of the burger, but it will take a little longer than a regular burger because it is so thick. This got pretty messy. It is important to make sure the edges are securely pressed because the cheese will ooze out and make a mess on the grill.

Finish it off with some marinara sauce on top. I used a brioche bun because I thought it would hold up better than a regular, thin hamburger bun.

Would it have been easier to just put the cheese on top and pour the sauce on? Yes definitely. But where is the fun in that? The thrill of biting into the burger and having the cheese ooze out absolutely makes this worth it.
