Mince the garlic cloves. Slice the onions into half-moons. Slice the pepper in half, remove the seeds and pith and dice the flesh. Dice the beef steak.
Put the beef in the bottom of a slow cooker.
Crush the caraway seeds in a pestle and mortar or spice grinder. Sprinkle over the beef along with the paprika. Toss to coat.
Top the beef with the sliced onions and diced pepper.

Pour the tomato sauce over the beef and vegetables and place the bay leaves on top.

Remove the bay leaves and stir in the parsley and corn starch mixture.
