Meatball Sliders

I have 15 pounds of ground beef in my freezer at the moment, and for a family of two plus a baby, that's a lot of beef! Both my grandparents and my parents have given us meat in the last few weeks. I really appreciate it; I never turn down free groceries! This is really lean, wonderful beef, and I've been looking for new recipes to try out with it. Something different from the usual standbys.

I found this on PW's site and made it that same evening. It came together really fast and was delicious! Plus, sliders are so cute...

1 lb. ground beef
1/2 c. panko or other breadcrumbs
2 cloves garlic, minced
1/2 tsp. salt
fresh ground black pepper to taste
1/2 c. milk
2 Tbs. olive oil
1/2 medium onion, diced
1 jar pasta sauce, your favorite
12 small dinner rolls
6 slices provolone cheese, each cut into 4 wedges

Mix meat with bread crumbs, garlic, salt, pepper, and milk. Knead together with hands. Roll into heaping tablespoon-sized balls. Heat olive oil in a large skillet over medium heat. Add onions and cook for one minute. Add meatballs between the onions and brown for one minute. (You might have to do this in two batches). Pour in jar of marinara; shake pan gently to mix. Put on lid and allow to simmer for 20 minutes.When ready to serve, cut each dinner roll in half. Place a wedge of Provolone on the top and bottom of each roll. Spoon a meatball with the sauce onto the bottom bun; top with the top bun.
