Preheat oven to 450 and grease a 12x15 inch cookie sheet. In a med. size bowl using a pastry blender, mix butter, flour and 1/8 teaspoons salt together until crumbly.
Using a fork, stir in Tabasco and banana.
On a floured surface, knead mixture gently adding a small amount of flour if necessary to make the dough firm.
Divide dough into half and roll out one half at a time on a floured surface until thin enough to cover prepared cookie sheet. Place dough on cookie sheet and sprinkle lightly with the coarse salt. Using a pastry cutter, cut through dough into 1" squares.
Bake 6-8 minutes or until lightly browned.
Remove crackers with a spatula and place on a wire rack to cool.
