Mini Meatball Sandwiches

This has got to be one of the cutest dinners we have had in awhile. Christopher wasn't home tonight so I was going to have a fend for yourself sort of night. We have more than enough leftover in the fridge. But Abby really wanted to have the minis tonight. She is so finicky and picky with food that if she shows the slightest interest I jump on it. I think she even ate more than me. These would be perfect for Sunday night football.

Ingredients
1 lb ground beef
1/2 cup panko
1 clove garlic, minced
1/2 tsp salt
freshly ground black pepper
1/2 cup milk
2 tbsp olive oil
1 medium onion, diced
1 jar (large) marinara sauce
12 dinner rolls
4 slices provolone cheese, cut into four wedges each
Directions
Mix meat with panko, garlic, salt, pepper, and milk. Knead together with hands. Roll into heaping tablespoon-sized rolls. 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, depending on the size of your skillet.) 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.
