How to make
Well-shaped fillet is carefully cut with a large sharp knife so as to obtain a sheet. Sprinkle with salt, black pepper and pour brandy, soya sauce and a little oil. Allow to stand for 2 hours, or so.
Meanwhile, in a pan, heat a little oil and fry chopped garlic, carrots, peppers. Once tender, add chopped spinach. Stir until the spinach deflates and season it with a little salt and pepper. Once filling has cooled, mix in grated cheese.
The filling is spread over sirloin and gently turned. To secure, you can pierce 2-3 places with pegs for teeth. Sirloin is moved to a greased tray at the bottom of which you cut the onion. The leaves are arranged on the bacon, so they overlap.
Cover with foil and roast sirloin for an hour in a 390°F (200 °C) oven. Then bake to readiness without foil.
