Toss ground beef, salt, black pepper, paprika, Italian seasoning, garlic powder, ground cumin, grated onion with its juice, and egg white together in a large bowl. Stir it up until everything's blended well.

Slice each mini pepper down the middle lengthwise and clear out the seeds to form little pockets. Fill each pocket with the meat mix, packing it evenly and flattening the top.

Set the stuffed peppers onto the oiled baking tray. Bake them for about 20 minutes or until the peppers get tender and the meat cooks thoroughly.

Sprinkle shredded mozzarella on each pepper. Pop them back in the oven for 3-4 minutes so the cheese melts nicely. Sprinkle some chopped parsley on top if you'd like before serving!
