Homemade Meatballs stuffed with Fresh Mozzarella

I enjoy looking online, specifically on other blogs, for meal inspiration.  I recently found a recipe for Homemade Meatballs stuffed with fresh mozzarella on the Picky Palate .  It was fabulous and everyone really enjoyed them.  Here's the recipe:

Ingredients:

2 tablespoons extra virgin olive oil
2 pound lean ground beef
1 large eggs
1 medium chopped onion
1 cup Panko bread crumbs
1/2 -3/4 cup fresh grated Parmesan cheese
1/4 cup milk
2 tablespoons minced garlic
2 tablespoon Worcestershire sauce
2 tablespoon yellow mustard
1/2 teaspoon kosher salt
1/4 teaspoon freshly ground black pepper
1 container of mini Mozzarella balls (bite size)

Directions:

Preheat oven to 350 degrees and spray a 9x13 inch pan with cooking spray.

Combine beef, egg, onion, bread crumbs, Parmesan, milk, garlic, Worcestershire, mustard, hot sauce, salt, pepper and garlic salt into a large mixing bowl and mix until combined.

Take 1/4 cup meat mixture and form into a ball and make an indention in the middle where the 

cheese ball will go.

Place a little cheese ball in the center.

Now mold the meat around the little ball of cheese and place in the baking dish.

Bake about 35 minutes, pour off excess beef juices as necessary until the meatballs are done.

Serve anyway you enjoy meatballs...we had Spaghetti and Meatballs - it was GREAT!
