In a large bowl combine the 1 cup of flour, yeast, sugar, and salt. Heat the water to 120 to 130 degrees F. Add the heated water and olive oil to the flour mixture mix in until well blended.
Add the cheddar cheese and sliced jalapenos and stir in. Continue to add the flour, mixing by hand until the dough is just slightly sticky. Knead the dough until smooth. Cover and let rise for about 1 hour or until the dough has doubled in size.
Grease a 10-inch cast iron skillet or a baking sheet. Once the dough is done rising form into an 8-inch disk. Place in the prepared skillet or baking dish. Let rest for 1/2 hour.
Preheat oven to 375 degrees F. Place the bread into the preheated oven after resting for 1/2 hour. Bake for about 20 minutes or golden brown.
Remove from the oven and set on cooling rack. Serve right out of the oven or cool.
