Here's a low-carb yet indulgent-looking dinner you don't have to feel one ounce of guilt about! Start by boiling the eggplant, then drain and cool. Saute together chopped tomatoes, garlic and onion. Halve the eggplant, and scoop out the flesh. Roughly chop the flesh, and add to the veggie saute. Stir in grated mozzarella and heat for a few minutes. Place the hollowed eggplant halves into a baking dish, and fill with the cheesy vegetable mixture. Top with more mozzarella, and bake for 20 to 25 minutes at 350 °F.
