If you're using frozen shrimp, first thaw them in cold water. Once the shrimp are thawed, start preparing the other ingredients.

Grate or finely chop the cheese.

Heat and spread the butter in a pan. After a moment, add the dried shrimp and peeled and crushed garlic. Season to taste with sweet paprika and chilli. Fry until the shrimp are cooked through, about 2-5 minutes (depending on the size). Stir and flip the shrimp frequently. Towards the end of frying, add finely chopped parsley. Mix well.

Toast the bread slices in a toaster or on a dry pan (on very low heat for about 3-5 minutes on each side).

On the prepared toasts, lay out the washed and dried arugula, shrimp, and cheese.
