Cut rye bread into slices. Heat some butter on the skillet and fry them on one side. Take the bread out of the skillet to cool down. Meanwhile, cut the onion into half circles and shred the cheese, if needed. Place the onion on the fried side of the bread, add a piece of bacon on top, cover with cheese and place the toasts back onto the skillet. Cover the skillet and cook the toast on low heat until the cheese starts to melt.
You will need:
- 8 pieces of rye bread
- 1 yellow onion
- 8 pieces of cooked bacon
- Shredded parmesan or smoked gouda cheese
