Let cream cheese and Boursin cheese sit at room temperature for 20 minutes until softened.
Dice Roma tomatoes and drain in a colander for 5 minutes to remove excess moisture.
In a medium bowl, combine diced tomatoes, chopped fresh basil, minced garlic, olive oil, balsamic vinegar, sea salt, and black pepper. Toss gently and set aside.
Spread softened cream cheese and Boursin onto serving platter using the back of a spoon to create gentle swirls.
Top evenly with tomato mixture, making sure to include all the flavorful juices from the bowl.
Right before serving, drizzle balsamic glaze in a zigzag pattern across the top.
Serve immediately with toasted baguette slices or crackers.
