You can make this as a regular sandwich and these are nicely made as an open-face-sandwich too.
2 tbsp cream cheese
1 1/2 tsp tomato ketchup
2 slices bread, flatten with a rolling pin (option to toast them slightly for bigger children)
30g cheddar cheese, thinly sliced or grated
Mix the cream cheese and ketchup together in a small bowl. Cut the bread into bite size or fun shapes. Spread half on to each slice of bread. Top with the grated cheese.
For a regular sandwich: Spread the mixed cream cheese and ketchup on to each slice of the bread. Add the grated cheese to one slice and sandwich with the remaining slice. Cut into squares or fun shapes.
