How to make
We put the slices on top of each other and cut the crusts with a sharp knife.
We smear them all with melted butter. Spread two slices with mustard, and two with lutenitsa.
We put the ham on the slices with mustard. Season with salt and black pepper.
We put the cheddar on the lutenitsa slices. We alternate the slices one on top of the other, turning the uppermost slice with the mixture facing down.
Cut the sandwich into 4 equal bites.
The mini sandwich bites with whole grain bread are ready!
