Remove the hearts’ bottom and mince.
Mix the cream cheese with mayonnaise, Parmesan cheese and mustard, incorporating well.
Add the artichoke bottoms and strawberries, both minced, and mix with a spatula in folding motions so the strawberries won’t break down.
Pour this mixture into a small oven-safe dish, strew 3 tablespoons of grated cheese and put in the oven until brown.
Take out of the oven and serve hot.
