Cut the tenderloin into slices about 2-3 cm (about 1 inch) thick and fry them in a thick frying pan or on a grill over medium/medium heat for about 3 minutes on each side.
Clean the asparagus with a peeler and cut off the woody ends, then cook it quickly over high heat in a pan heated with a little butter, salt and pepper. As soon as it starts to soften and turn color, take it off the heat.
Cut the tomatoes and onions into rounds and season them well with salt, pepper, oregano and olive oil.
Plating is as simple as the recipe. We also added a freshly baked focaccia and embellished the table with a bouquet of flowers from the garden. And if it's served for dinner, a glass of red wine is more than welcome.
