Preheat the oven to 350 degrees.
In a medium bowl combine the flour, masa mix and salt.
Cut in the olive oil and then stir in the water.
Take a tangerine-sized ball of dough and roll it out on a floured surface until it is 1/8-inch thick.
Place spinach, tomato, black beans and cheese in the center of the dough.
Sprinkle with cumin and chili powder.
Fold the dough over so it looks like a calzone and press the edges together with a fork to form a seam.
Brush with olive oil and bake on a cookie sheet for 20 minutes.
