Preheat oven to 375 degrees.
In a baking dish, combine cream cheese and goat cheese . (Let sit at room temperature for 30 minutes before hand).
Mix in garlic, chives, scallions, salt, pepper, and 1 tablespoon olive oil. Stir to combine well.
On a baking sheet, toss the chopped cherry tomatoes with olive oil, balsamic vinegar, salt and pepper. Toss to coat.
Bake the dip and the tomatoes in the oven, uncovered for 10 minutes. When done, the dip will be just slightly browned on top and the tomatoes will be just starting to blister.
Remove dip and tomatoes from oven. Spread the tomato mixture on top of the dip.
Serve hot with tortilla chips for dipping.
