Heat a large skillet with tall sides over low heat. When the skillet is hot, add the olive oil and tomatoes. Adjust the heat slightly to low-medium, but not so high that the oil pops. Cook for 5 to 7 minutes or until the tomatoes begin to soften and blister. Use a wooden spoon to press gently on the tomatoes and smash them flat. The soft insides will mix the olive oil. While the tomatoes soften, prepare the pasta.

Cook the pasta according to package directions. Drain, making sure to reserve ¼ cup of the pasta water, set aside.

After the tomatoes have softened and blistered, add the salt, pepper, and garlic. Continue to cook for another 30 seconds to 1 minute until the garlic becomes fragrant. Pour the broth, and stir to combine. Increase the heat to medium and allow the mixture to simmer until the liquid is reduced by half, about 7 to 8 minutes.

Remove from heat, and toss with the cooked pasta noodles, balsamic vinegar, and fresh basil. If the noodles appear dry, add a little bit of the reserved pasta water. Add the mozzarella pearls last. Serve with additional fresh basil and mozzarella pearls if desired. Store any leftovers in the refrigerator for up to 3 days. Enjoy hot or cold.
