Basic meatballs

  • Combine breadcrumbs and milk and leave to swell.

  • Pour in the balsamic vinegar and allow to reduce.
  • Add the honey, mustard and caraway seeds and stir well. Add the barbecue sauce and water and simmer for 2-3 minutes.
  • Add cooked meatballs to the sauce and heat through.
  • Serve the saucy meatballs in fresh ciabatta or sourdough rolls and top with grated tasty cheese if desired.


The key to making these sandwiches sing is the Homemade Beef Meatballs. They’re super easy to whip up, so don’t get put off at the thought of having to slave away rolling them from scratch.
The other component is the sticky, caramelised honey mustard onions. They are mouthwateringly sweet with a tang of balsamic to help cut through the richness.
Serve your subs topped with cheese (if you like) next time you’ve got a few mouths to feed. Think a relaxed dinner party, movie night or when you have people over to watch the big game.
Add a salad like my Kumara, Bacon, Walnut and Orange Salad to the spread if you’re keen to keep up with your 5+a day.
