Season the roulades with salt and pepper, brush with mustard and put a slice of bacon on each.
Peel and slice 1 onion, clean the carrot and celery stalk and divide each into 4 sticks. Cover the meat slices with pickles, carrots, celery and onion rings, roll up and secure. Fry well all around in the roasting pan. Clean the remaining onions and soup vegetables, cut into small pieces and fry briefly with the roulade.
