Combine spices in a small bowl. In a large bowl, toss the diced potatoes with olive oil and spice mix.
Spread potatoes on a greased cookie sheet.
Bake for 25-30 minutes, stirring halfway through.
You can decrease the oven temperature and increase the cooking time in order to cook other recipes at the same time. For each 25 degree decrease in oven temperature increase the cooking time by 5-10 minutes.
