Rub the pieces of beef sirloin with salt and pepper. Fry in a pan as you like - bloody, medium or well done. Prepare fries according to package instructions. Mix coarse salt with chili.
Cut beef sirloin into 1-1.5 cm slices. Serve with fries sprinkled with a mixture of coarse salt and chili. The best it's to serve the dish on paper or newspaper - all for best visual effect. Additionally, just a small bowl of mayonnaise.
Serve horseradish sauce instead of mayonnaise.
