1-In a pot mix cheese sauce and we boil it on a fire until melted then raise

2-In another pot we saute the onions with oil and add sugar, salt and cover and leave on a low fire while stirring from time to time for about 20 mins

3-Its best to cool the meat so it's easier to cut into slices and hammer on the surface and spread on it black pepper, salt and saute in a fryer on a fire on each side a minute and a half

4-We toast the bread and spread the sauce on it, the place the meat, caramelized onion and last thing the cheese sauce again and parsley

Bon appetit
