In a large bowl, combine yeast, water, and sugar. Stir and let it rest for 5 minutes.

In a small bowl, combine olive oil, garlic, and half the salt.

Pour half the oil mixture into the yeast mixture. Set the remaining oil mixture aside.

Add flour to the oil and yeast mixture and stir to combine.

Add dough to a greased bowl, cover with a tea towel, and let it rest for 1 hour or until doubled in size. Meanwhile, caramelize the onions in a skillet over medium heat with the remaining salt. Cook until softened, about 20 minutes.

Preheat oven to 450°F. Pour the reserved oil mixture into a 9x11-inch baking dish and coat with a pastry brush.

Work the dough into the dish, creating dimples with your fingers. Top with caramelized onions and shredded cheese.

Bake for 18-20 minutes until golden brown and cheese melts. Serve warm.
