The dressing for this roasted tomato pesto pasta salad recipe uses the leftover tomato juices from the baking dish along with roasted garlic, basil pesto and balsamic vinegar.
In a rectangular baking dish, whisk the olive oil, balsamic vinegar, salt and pepper. Stir in the tomatoes and garlic cloves, arranging the tomatoes cut-side up. Roast for 30-35 minutes until the tomatoes have deepened in color and have slightly wrinkled. Use a slotted spoon to transfer them from the pan to a plate, leaving the oil mixture in the pan.
Cook the pasta in salted boiling water until al dente according to package instructions. Drain the pasta and rinse with cold water in a colander.
In large bowl, squeeze the garlic cloves out of their skins and mash and stir them into the pesto and the oil mixture from the roasting pan.
Stir the pasta into the dressing.
Add the roasted tomatoes, mozzarella, pine nuts, chives and basil.
Stir everything together.
