I found this recipe online. It looks like the one I was talking about:
EGGPLANT MEATBALLS
1 large eggplant, peeled and diced
2 lbs. lean ground beef
1 cup parmesan or romano cheese
3 cloves garlic, crushed
1/2 cup bread crumbs
2 eggs
1/2 tsp. basil
Salt and pepper to taste
2 tbs. olive oil
1 cup spaghetti sauce
3/4 lbs. Muenster cheese, thickly sliced
Place the diced, peeled eggplant in a saucepan with enough water to cover. Bring to a boil, reduce the heat and simmer for 10 minutes until the eggplant is tender.
Meanwhile, mix the beef, garlic, breadcrumbs, eggs, basil, salt, pepper and 1/2 cup parmesan cheese in a bowl. Drain the eggplant and allow it to cool. Mash the eggplant and mix it to the meatball mixture. Form into 18 meatballs.
In a large frying pan brown the meatballs on all sides. Place the spaghetti sauce in the bottom of a large baking dish. Set the meatballs in the sauce. Top with the remaining parmesan cheese and finely with the thickly sliced Muenster cheese. Bake in a 375 degree oven for 20 minutes or until all is hot and bubbly.
