Using 2 wooden spoons placed either side of the vegetable as an aid, cut into the eggplant at equal intervals. The wooden spoons stop you from cutting right through the eggplant. The slices should be about ¼-inch thick.
Brush the pesto inside each gap in the eggplant.
Chop the tomato and mozzarella into slices and insert them into the gaps together with the ham. Place the filled eggplant in a casserole dish, pour some olive oil on top and bake at 325°F for 45 minutes.
Garnish the cooked Eggplant Hasselback with basil, parmesan and roasted pine nuts.
