Preheat the oven to 400°F. Spray a baking sheet with nonstick cooking spray or line with parchment paper.In a large bowl stir together the yeast, brown sugar, and warm water. Let is sit for about 5 minutes. this allows the yeast to bloom.Stir in the flour, olive oil, and ¾ teaspoon of the salt until the dough just comes together. Lift it from the bowl and form a ball. There will be a few shaggy straggly pieces - just press those into the dough with your fingers.Place the ball back into the bowl, place the bowl on top of the preheating oven, and cover with a towel. Let the dough sort of proof for about 25 minutes.Scatter a little flour on a clean work surface. Turn out the dough and knead 3-4 times. Divide into 4 equal pieces and shape each piece into a ball.Brush a little olive oil on top of each ball. Sprinkle with the remaining salt. Then use a sharp knife to slash an 'X' on top of each ball.Place each round on the prepared baking sheet and bake for 25-30 minutes. They will be a pretty golden color and will sound hollow when tapped.To serve, cut the top off each bowl and then pull the soft inside of the bread out, leaving the crust in tact. Fill with your favorite soup and then serve with the soft bread insides.
