To make the pizza dough, follow the recipe from Food 52 (linked above) but use a baking sheet instead of a cast iron skillet.
About 30 minutes before baking, place one rack at the bottom of the oven and one toward the top (about 4 to 5 inches from the top heating element). Pre-heat the oven to 450°F.
When you’re ready to bake the Garden Focaccia, drizzle some olive oil evenly over the pizza dough and then season with salt.
Decorate: using all the vegetables, have some fun creating a garden! Create flowers and anything you want. Feel free to fill up all the dough or leave some parts uncovered. It's up to you! Just have some fun making a garden.
Bake the Garden Focaccia on the bottom rack of the oven for about 20 to 25 minutes, until the bottom and edges of the crust are golden brown.
Remove from the oven and place the pan on a heatproof surface. You may need to use a knife or spatula to loosen the Garden Focaccia from the baking sheet but it should be pretty easy to do. Cut and enjoy!
