1/4 cup bread crumbs
3 TBSP low sodium soy sauce
1 garlic clove, minced
1 pound ground beef
3 medium carrots, peeled and cut into thin bite sized strips
1 medium yellow onion, thinly sliced
2 TBSP brown sugar
9 oz fresh spinach
4 hoagie buns
In a large bowl, combine the egg, breadcrumbs, 1 TBSP soy sauce, and garlic.
Add the ground beef and mix to combine.
Form 30 meatballs.
In a very large skillet over medium heat, arrange the meatballs in a single layer and cook for 8-10 minutes, turning occasionally, until browned on all sides.
Remove the meatballs from the skillet and keep warm.
Add the carrots and the onions to the skillet and cook, stirring occasionally, for 3-5 minutes.
Return the meatballs to the skillet and add the brown sugar and remaining 2 TBSP soy sauce.
Cook 2 minutes more, or until everything is well coated in sauce.
Add the spinach and cook about 3 minutes, or until the spinach is just wilted.
Divide the mixture among the hoagie buns.
