Instructions

  1. In a large skillet over medium heat, brown beef until no longer any pink; drain.
  2. Add onions and garlic and cook until onions are transparent.
  3. Add remaining sauce ingredients and stir to combine. Bring to a simmer; reduce heat and simmer until thickened (about 15 minutes).
  4. Meanwhile, split buns and spread with butter. Place on a baking sheet and sprinkle with garlic and parmesan cheese. Place under broiler and broil until toasted golden brown. Set aside until sauce is done.
  5. Taste sauce and correct seasonings, if needed. Serve with toasted buns.
