Roast Beef Sandwich
Prepare the roast beef 1 day ahead.
Preheat oven to 200ºC.
In a pan, heat olive oil until very hot and add the rump roast. Seal it on all sides so it is just cooked on the edges. Remove immediately and place in aluminum foil.
Cover the rump roast with mustard and garlic paste and season with salt and pepper to taste. Seal well with more aluminum foil. Cook in the oven for 10-15 minutes. Let sit for 15 to 20 minutes and then refrigerate in aluminum foil for 1 day.
Slice the roast beef in very thin slices.
Cut each piece of ciabatta bread and drizzle olive oil on them. Spread mustard on one side of bread and add avocado, then meet and top with green beans and tomato slices. Serve promptly.
