Slice half of the tomatoes*, and then place all of the tomatoes into a bowl and drizzle them with oil and honey. Add the sliced red onion to the bowl, and then place mixture onto a nonstick or foil-lined baking sheet.
Roast tomatoes for 15-20 minutes, or until tomatoes have burst.
Pour tomatoes into a bowl, add fresh mozzarella, thyme, salt, and pepper and enjoy!
*I only sliced half of the tomatoes because I like the variety of sliced and whole tomatoes, but if you prefer all sliced tomatoes then slice all of them!
