I love what homemade bread does to a sandwich. You can take a simple sandwich and make it outstanding just by using homemade bread.
3 cups bread flour, plus more for dusting
2 tablespoons olive oil, plus more for brushing
Stir the yeast, sugar and 1-1/2 cups warm water (about 110 degrees) in a bowl. Let sit until foamy, about 5 minutes. Whisk the flour and 1-1/2 teaspoons salt in a large bowl. Add the yeast mixture and olive oil and mix with your hands into a smooth dough.
Cover the bowl with plastic wrap; set aside in a warm place until the dough doubles in size, about 1 hour.
