Preheat oven to 500°F.
Place the dough in a large bowl and add the seasonings (garlic powder, dried oregano, dried basil, and dried thyme) and salt. Knead until the seasonings and salt are well incorporated.
Roll the dough out onto a floured surface. Use your fingers to lightly press the garlic slices into the top surface of the dough. Bake the focaccia until the dough is puffed, blistered, and browned, about 8-10 minutes.
Remove the focaccia from the oven and lightly brush it with olive oil (optional). Top it with the tomato halves, chopped basil, and a pinch of salt to taste.
Tip: If you’re looking for a heartier meal, spread some Pistachio-Basil Spread on the focaccia before adding the tomatoes and basil, or, make the Zesty Tomato-Basil Bruschetta and spread the bruschetta on the focaccia.
