Sauté onions and garlic in a pan over medium heat until just translucent
Add 1 tsp of the Italian seasoning and a little salt and pepper, mix and then remove from heat and set aside to cool slightly
Preheat oven to 400°F
Using a mandolin or sharp knife thinly slice the remaining vegetables
Lightly spray a large pie pan or baking dish with oil and spread the onion and garlic mixture evenly around the bottom of the pan
Alternate the vegetables around the edge of the baking dish and then continue moving inwards until the dish is full
Sprinkle with salt and pepper and the remaining Italian Seasoning
Cover with foil and bake for 30 minutes, then check to see if the veggies are cooked through, they may need an extra 5 or 10 minutes depending on the thickness
Remove the foil and top with the Italian Cheese Blend, then place back in the oven for 10 to 15 minutes or until the cheese has melted and browned slightly
Let rest 5 minutes before serving
Notes
Cheese - We use a blend of Mozzarella, Provolone and Parmesan but have also used just fresh mozzarella slices. It doesn't look as pretty once baked but the fresh mozzarella is a nice touch!Seasoning - Use a good quality Italian Seasoning and you can use more or less depending on your tastesExtra Veggies - If you have any veggies left over just toss them with some olive oil and salt and pepper and put them on a parchment lined tray. Bake with the Tian in the 400 degree oven for about 15 minutesSlicing - You can use a Mandolin to slice the zucchini, squash and potatoes if that is easier, or a sharp knife
