Steps
1
Preheat oven to 400°F. In large bowl, combine ground beef, garlic, bread crumbs, Parmesan, egg, salt, and pepper. Form mixture into 12 meatballs. Place onto parchment-lined baking sheet and bake 20 min., until fully cooked.
2
Meanwhile, in deep 12-inch skillet, melt butter on medium-high. Add mushrooms and cook 15 min., until golden brown, stirring occasionally. Season with salt and pepper. Drain any excess liquid.
3
When meatballs are done, preheat broiler. Cut 4 hoagie rolls lengthwise, without cutting completely in half, and remove some of the insides. Place on baking sheet and drizzle inside of bread with oil. Divide meatballs, mushrooms, and provolone between each roll.

Broil 3–4 min., until cheese is melted. In small bowl, toss arugula and vinegar to combine. Top sandwiches with arugula and serve.
