Pasta with roasted eggplant and tomato purée

We followed this recipe: https://smittenkitchen.com/2008/01/rigatoni-with-eggplant-puree/ Our modifications: 2 small Asian eggplants; 1 lb (1 1/3 pint) Campari tomatoes, quartered; 1 bulb garlic (peeled); and 1 lb penne (instead of rigatoni). We toasted the pine nuts at 325 in our toaster oven until lightly browned (about 3 mins). We also finished the pasta with a glug of balsamic and the juice from half a lemon for brightness. (Jan. 2017)
