Begin with the marinade. Add the olive oil, balsamic, garlic, mustard and sugar to a bowl and whisk to combine.
Add in the sliced tomatoes and torn basil. Mix together, taste and add salt and pepper to your taste. Set aside in the fridge until ready to serve.
Place softened cream cheese in a small bowl and with a fork break it up until smooth. Add in the Parmesan cheese and salt and pepper to taste. Mix to combine thoroughly. Place mixture into a piping bag or a plastic bag with the tip cut off. Pipe cream cheese mixture into phyllo cups distributing the mixture evenly.
Top the cream cheese with the tomato bruschetta mixture, serve immediately and enjoy!
