Ingredients​

SANDWICH​

• 3 beef New York (top loin) steaks
• 5 tbs olive oil
• 12 slices wholegrain bread
• 225 g cheddar cheese thinly sliced
• 2 bunches watercress stems trimmed

CARAMELISED ONIONS AND HORSERADISH SAUCE​

• 2 tbs olive oil
• 2 onions large thinly sliced
• 4 sprigs thyme
• 2 garlic cloves finely chopped
• 1/2 cup horseradish
• 1/4 cup mayonnaise
• 1/4 cup sour cream
• 1 pinch salt and pepper *to taste

Method​

1. To caramelise onions and make horseradish sauce: Heat large heavy skillet over medium-high heat. Add oil, then add onions and thyme; saute for 15 minutes, or until onions are golden brown.
2. Add garlic and saute for 2 minutes, or until beginning to soften. Remove thyme stems. Season with salt and pepper. Remove from heat.
3. In bowl, mix horseradish, mayonnaise, and sour cream. Season with salt and pepper.
4. To make sandwiches: Season steaks with salt and pepper, and coat with 1 tbs oil. Barbecue steaks over medium-high heat for 3 minutes per side for medium-rare. Transfer steaks to a carving board and rest for 5 minutes.
5. Brush both sides of bread slices with 4 tbs oil. Barbecue on one side for 2 minutes. Turn bread over and divide cheese among 6 slices. Close bbq hood and cook until cheese melts, about 2 minutes.
6. Spread 1 tbs horseradish sauce over each of 6 slices without cheese. Trim fat and sinew from steaks, then thinly slice steaks across grain. Divide steak among sauce-topped bread. Top with onions, more sauce, watercress, and remaining bread slices, cheese side down.
