Roast pine nuts in a pan without fat. Take them out, let them cool down a bit and chop them roughly. Wash basil, shake dry and chop the leaves of 4 stems finely. Drain the sardines and chop them with a fork.
Mix the goat cheese, milk, pine nuts and chopped basil. Fold in sardines, season with salt and pepper. Wash and slice the tomatoes. Alternately layer 3 slices of tomatoes and cream cheese cream.
Finish with a dash of cream cheese cream and basil leaves.
