Hunter's Hero (meatball sub) from Guy Fieri

These were an awesome superbowl food! I was impressed with myself.
2 T olive oil
1/2 red onion, chopped
1 red bell pepper, chopped
5 cloves garlic, pressed
1/2 cup milk
3/4 cup bread crumbs (I used 2-3 slices of white bread & tore them up)
1 lb. ground beef
1 lb. ground pork sausage
2 tsp dried oregano
1 tsp red pepper flakes (I used just a pinch!)
1/2 tsp salt
1/2 tsp pepper
1 egg, beaten
7 hoagie rolls
marinara sauce
slices of mozzarella
1/4 cup parmesan
Heat 1 T oil in large skillet over med. heat. Cook onion, bell pepper and garlic till tender, 5 mins. In bowl, pour milk over bread crumbs and stir till milk is absorbed. Add sauteed veggies, beef, pork sausage, oregano, red pepper flakes, salt, pepper and egg. Mix well. In same skillet used for veggies, heat remaining oil over med.heat. Form large meatballs, and drop into hot skillet. Brown on all sides and cook thoroughly, till juices are clear and meat is no longer pink. (This takes some patience.) On each hoagie roll, place 4 big meatballs, pour some marinara sauce (1/4 cup), couple slices of mozzarella, and sprinkle with parmesan. Put on cookie sheet and Broil in oven till toasty and melty. Enjoy!!
