Ingredients

Instructions

  1. Step 1: Heat a grill pan over medium-high heat. Cook 4 large pork sausages for 10-12 minutes, turning frequently until browned and cooked through to an internal temperature of 160°F (71°C). Remove and set aside.
  2. Step 2: In a medium skillet, melt 2 tbsp butter over medium heat. Add 1 large thinly sliced yellow onion, 1 tbsp brown sugar, 1 tbsp balsamic vinegar, 1/4 tsp salt, and 1/4 tsp black pepper. Cook for 15 minutes, stirring occasionally, until onions are deeply caramelized and sweet.
  3. Step 3: Lightly toast 8 slices of white bread until golden and warm. Spread 2 tbsp mustard evenly across 4 slices and 2 tbsp tomato sauce on the other 4 slices.
  4. Step 4: Assemble each sandwich by placing one cooked sausage on a mustard-coated slice of bread, topping with 6 slices of cooked beetroot, then spooning generous caramelized onions over the beetroot. Close sandwiches with tomato sauce-coated bread slices.
  5. Step 5: Press sandwiches gently, slice in half on the diagonal, and serve warm.
