Cut an eggplant into round slices. Put on paper towel & salt. Let stand so some of the water comes out of the eggplant. Grill eggplant to brown on both sides in pan, season with salt/pepper. Spray baking dish with cooking spray & put grilled eggplant slices along the bottom of the pan.
In food processor, blend either basil or pesto with olive oil & a garlic clove. Spread this mixture onto eggplant. Top with sliced tomatoes. Sprinkle feta atop the eggplant/tomatoes, drizzle with olive oil & sprinkle with salt/pepper. Bake 350degrees until lightly browned. DELICIOUS on salad, as side dish, or on top of pasta. Refreshing, you could also garnish with basil strips.
I don't have the best camera to display how beautiful & delicious this was, but trust me, it was DELISH!!! Enjoy!
