Preheat the oven to 375 degrees.
Mince your garlic and using a sharp knife, slice your zucchini, eggplant, tomatoes, and onions into 1/4 inch thick circular slices.
Mix together olive oil and herbs in a small bowl (olive oil, basil, parsley, thyme, salt and pepper sprinkle) and set aside.
In a 10’’ skillet over low heat, add tomato sauce with some salt and pepper and bring to a bubble, about 2-3 minutes. Turn the heat off.
Take one slice of each vegetable (zucchini, eggplant, tomato) and starting at the rim of the pan, start arranging vegetables into a spiral. Add in your onion slices every so often. Continue around the entire pan, moving to the center and continue to fill vegetables in a circle, overlapping them.
When the skillet is full, top with the herb olive oil mix. Cover the skillet with tin foil and cook for 35 minutes.
Remove from the oven and ENJOY!
