Hot Dog with Sausage and Mustard Mayo
·Marinate the sausages
The day before, marinate the sausages in a mixture of spices and oil.
Caramelise the onions
Peel the onions and slice into rings or half-moons. Heat some lard in a pot and add the onions. Cook over medium heat until golden, then continue until light brown. Season with salt and pepper. Add a splash of water if needed.
Mix the mustard mayo
The caramelised onions will keep in the fridge for several weeks, so feel free to make a batch ahead of time. Stir the mustard into the mayonnaise.
Split and toast the buns
Slice the hot dog buns open and toast lightly on the grill. Grill the sausages until nicely crisp.
Serve
Spread mustard mayo inside the sliced bun, then add a spoonful of caramelised onion, some cucumber slices and the sausage. Top with your favourite salad leaves and tomato slices, if you like.
